First of all. Always make a backup of your work..Never work on the only copy you have! <---Real important!
Create a new folder (somewhere else) and copy everything to that folder.
Do you have you something embedded, which isn't there on your computer anymore?
It doesn't have to mean, that the fla file is corrupt.Just that what flash expected to find
isn't there...It could be you're missing software like Photoshop, if you have embedded PSD
files, Excel if you're using the xls.. a.s.f...Make sure, that everything you need is there
on your computer.
Hope you solve the problem
In what version of Flash were the flas created? Try opening them with this version. You can try also to import the swfs, if you have not protected them. And yes, always store more version of the fla.
Version was CS5. You did not specify WHAT VERSION to try and open the files with, which version?
Message I sent to ADOBE after they dug into my RUINED flash file and lost more than 100 hours of design time... I am so PISSED OFF I cannot see straight! I cannot believe they are actually selling CS5 with the known problems... The software DOES NOT WORK!Thank you... but seriously Bro this is absurd. You tell ADOBE couldn’t take another 6 months and BETA this out? Does ADOBE realize there design software is more expensive than everyone else's? And it should perform as such and this problem is not a small issue, my system crashes constantly ruining files that may have hundreds of design hours invested and ADOBE is selling this version?I am making a FORMAL REQUEST that ADOBE STOP selling CS5 until these bugs are worked out. Tell the if they feel that’s not a good idea ask TOYOTA how that’s working out for them? Designers like me put so much time into our work there is NO WAY I will risk losing what could amount to ten-of-thousands of dollars in design time by working in CS5. You have forced me to sit aside the money I invested in CS5 because I cannot trust the build! How can ADOBE knowingly sell CS5 with these errors? The software does not WORK!-Kevin
I've just come across the same problem.
I purchased CS5 for Windows 7 and started working on a site that was built in CS4. When I saved it the first time, it gave me the option to save it in CS4 or CS5 format. I saved two copies, one in each format. Every time I've saved my progress, I've done the same thing. Saving multiple copies of a .fla file is helpful under any other circumstance, but it's useless in this one because Flash suddenly decided it didn't feel like opening any of them today.
I tried opening the same file I've been working on for days and it said "Unexpected file format. Can't find file: [file name]." It opened everything with no problems yesterday and every previous day, but today it gave me this message. It seems like a lot of other people have been having this issue and I really hope someone can offer some advice.
PS, here is the exact message:
Unexpected file format.
Cannot find file J:\WebsiteFiles\CBW Source_Files\Source Files\site_reorganized_CS5.fla.
Okay. Strangest thing ever:
I just spent an hour on the phone with Flash tech support only to have them tell me that it was a file issue and had nothing to do with the program. I created a new .fla document, saved it, and it re-opened fine. Their only explanation was that "your files have been corrupted and the program is working perfectly fine, sorry," with no explanation as to WHY they were suddenly being rejected by Flash.
But that's not the best part.
After I hung up, I restarted my computer and just out of desperation tried to open the corrupted files again. THEY WORKED PERFECTLY FINE. I'm starting to think this program is simply possessed.
Sorry your issue hasn't been resolved, OP. :/
Fla files like every other type of file can and do corrupt. The causes are different: lost fragments of data, bad HDD sectors, etc ....
This is one reson for possibly not being able to open your file.
Another is if the file was created with more recent version of Flash and you're trying to open it with an older version. It is usually then when the "unknown file format" message appears
I myself have never had this type of problem with my own files for years ... The only time it happened to me was when I handled a file of my client, which simply may have been poorly treated. This is one in thousands if not more error ...
I am also using CS5 flash at work with windows 7. I quickly learned to save multiple versions of the same file. It is still incredibly annoying to have it crash while saving and corrupt my files 6 or 7 times a week and I still lose work. Flash CS5 is inexcusably unreliable and buggy. Please come up with a solution to this problem as soon as possible. It is interfering with my productivity at work.
WinXPSP3, same problem encountered.
Have filed a bug report, still not heard anything. Last time I trawled through Adobe's support service it ate through 7 hours of my dev time (and therefore budget).
Since I can no longer create basic SWF export because of;
- Inconsistent export outcomes; pixel positions of a non-dynamic MovieClip, on stage, differs every time
- Re-draw problems with masks when working on the Stage; sometimes they disappear, sometimes they don't apply on export
- Random program crashes when datatype-hinting kicks in
- Custom classes not compiling (Not a network-related problem here)
- Old skool tweening engines (Zigo) not exporting (though recognised and error-free)
- Can't open source files created in the same version as the IDE which fails to open said files
As with the last bullet point, and the title of this post, the "Unexpected File Format" error has been the last straw. This camel's back is broken. Just now I heightened my Adobe experience by failing to install CS5 on Vista because of "Error with Component Dependencies" -- but only after clicking 20 or 30 times to actually download the Akamai download manager -- whatever.
As technical lead at our company, I have now begun strongly advising against production of any serious work when the requirement involves working with what, in my opinion, is now this demo-only "show your friends" piece of software -- Flash CS5.
My tether breaking: -----~ ~-----
I changed the .fla file to a .zip file, tried to extract it and both WinZip and WinRAR threw errors around some 'DOMDocument.xml' file being corrupt, output log:

Guess what. I just randomly stumbled upon this thread when my gf was experiencing problems with a .fla file created in Adobe Flash CS 5, on a Windows 7 64bit machine, which for no apparent reason started throwing the "Unexpected file format" error.
Some guy before me suggested that the file is indeed just a renamed archive (.zip)...
So... I renamed the file to [filename].zip, opened it in winrar and pressed ALT + R (tools -> Repair archive) after the winrar process had thrown an "Unexpected end of archive" error.
It then created a file named rebuild.[filename].zip, which i just renamed to rebuilt.[filename].fla and...
Presto! It works perfectly in Adobe Flash CS5 again.
I hope this information will be able to solve further problems for people with corrupted .fla files.

Hey Wertisdk1! I tried your ways with my particular corrupt fla. It didn't really worked, but it gave me a good idea, which in the end led me to recovering at least half of my "lost" work. 2 Days of hard frame by frame animation was in risk! Thanks!
So here's what I did, perhaps it can help some one. Took me a few tests and tries but in the end it was good. You can recover your lost SYMBOLS. Its a way of getting back all your project library into a new flash file. It goes like this:
1) I opened my corrupt fla file using Winrar. It shows a couple of folders and a few XML files, that can and will be opened later using notepad or word or whatever text editor.
2) I extracted all those files into a new folder with the name of my corrupted file. eg: c:\documents\corrupted.
3) Once 'decompressed', I opened the LIBRARY folder (eg: c:\documentscorrupted\LIBRARY\), in which all the symbols in my corrupted project are apparently stored as xml's. I backuped this files for later. This are my original symbols I want to be restored.
4) In Flash CS5, I started a new project, exactly the same size and specs of the corrupted one. Create a symbol in it and name it with some name you can remember, like recovery. Just any symbol, a graphic or a movie clip, whatever.
5) Once the project looked exactly as if I was going to start drawing all over again, I saved the file, with a new name eg: correputed_file_NEW.fla
6) I go and open this new 'correputed_file_NEW.fla' using again WINRAR and once again uncompress the whole fla into a new folder. eg: c:\documents\corrupted_file_NEW\
7) Go to that folder and open DOMDocument.XML using notepad, dreamweaver or whatever text reader you have. You'll see a long HTML code. Focus on the 7th or 8th line, you'll see <symbols> and then a list of the symbols in your fla, which in this case would only be that "recovery" we just created.
<Include href="recovery.xml" itemIcon="1" loadImmediate="false"/>
Also, in the Folder you have your correspondent LIBRARY folder, in wich you'll see 'recovery.xml' (c:\documents\corrupted_file_NEW\LIBRARY\)
8) Now its time to get your backup symbols from the corrupted file, the symbols I want to restore, and copy them into the Library folder of my "correputed_file_NEW.fla" (c:\documents\corrupted_file_NEW\LIBRARY\), without deleting 'recovery.xml'.
9) Go back to DOMDocument.XML on your text editor. Now you need to add the name of every symbol restored. The same way you see here (recovery files named bass1, bass2 and so on):
<Include href="recovery.xml" itemIcon="1" loadImmediate="false"/>
<Include href="bass1.xml" itemIcon="1" loadImmediate="false"/>
<Include href="bass2.xml" itemIcon="1" loadImmediate="false"/>
Once done, Save changes on DOMDocument.XML
10) Goto the folder c:\documents\corrupted_file_NEW\, select all this files and folders and "compile" them again using Winrar. This is done by selecting them all, right click and "add to archive..." OR straight from Winrar, look for the files, highlight them and click on 'ADD'.
11) Name your file 'recovered project', Choose ZIP as 'File Format'. MAKE SURE you cahnge the name from 'recovered project.ZIP' to 'recovered project.FLA'.
12) Click ok and watch your fla get compiled again.
13) Open this new recovered project.fla using Flash and wow!
In my case, I recovered all the symbols in which layed a lot of the work I almost lost during the file corruption! I still have to start overall the timeline work, but when everything seemed lost, this helped me a lot!
Sorry for my english, is not my native language. I hope my instructions made sense and I helped out somebody.
Having a corrupt fla is a pretty horrible thing to have. Specially when you obviously didn't made a backup of the file, obviously! And see with horror hours, days or weeks of work just die... or worse! Stay in coma!
the same issue here,
CS5 crashes and gives a message "UNEXPECTED FILE FORMAT"
new instal of CS5 on Windows 7 64 bit, good workstation,
stable network in a hi-tech company
it doesn't look like a plain corrupeted file, happens too often
it seems that Flash CS5 is less stable than the previous editions

I had the same Problem and found a solution that works for me.
First, copy your corrupted FLA into a new folder. Rename your FLA to [Your File].zip. Then Open that ZIP File with WinRAR and press Alt + R to repair the Archive. Extract the content of the fixed new ZIP file into another folder.
Now, open the "DOMDocument.xml" in Safari. In my case, Safari throws a XML Error. I opened that XML with an Editor and found a non UTF-8 Char at the Line where Safari throwed the error. I deleted that Char, saved the XML and opened the XFL File. Everything works fine.
Where did that non UTF-8 Char came from? In my case, i copied same Text from Powerpoint into a component property field. And everybody should know, that copied text from MS Products comes with a lot of garbage, that nobody needs. Flash saves your texts with that garbage in a xml and your FLA is coruppted.
:SOLUTION: Windows 7
Go to C:\Users\YOURUSERl\AppData\Local\Adobe\Flash CS5.5\en_US\Configuration
This place have some .FLA named TMPsgv1zqm92r or something.
Open ALL and find your pretty .FLA untouchable!
Then save and backup! and BE HAPPY
Today we have released Flash CS5.5 update . This update contains fixes for opening and saving some Flash Professional files (FLAs) in CS5.5, and other bug fixes.
Please download Flash CS5.5 updater .
You Can download from Flash > Help > Updates .
Had the same problem, however using tips included in above posts I managed to work out a way to recover content of corrupt .fla files:
1. Open WinRAR
2. Select the *.fla file and click the "Repair" button and choose to treat the archive as a .zip file
3. WinRAR created rebuilt.*.fla file. Open it.
4. The file seems to work now, but generating swf may not work. From here you can just copy/paste the clips and code to new, empty document.
I know that this is an old topic; however we are having a major issue with this.
Our version of Flash is fully up to date with the latest patch 18.104.22.1689.
Yes we are using this software in a network environment and are saving to a network location. However we have started to save to memory pens which also seem to fall to this bug or design fault within Flash.
From being an educational establishment for security reasons giving students access to the actual computer is not advisable.
Is adobe going to look at making flash and other products more suitable working in a network environment? As you can imagine we are training our students to use your software now so that when they leave they are adapt and confident to continue using your software!
Has anyone found a work around for this issue?
We are thinking of deploying a virtual hard disk that the students can access which will be stored locally on each computer.
Will this help resolve this issue or get around it?
I'm also still having the same problem here...
If this program is on a beta version why it was released?!?!

I have just recovered a file for one of our students.
If you are running Windows, rename the file from something.fla to something.zip
Download this program http://www.diskinternals.com/zip-repair/ and repair the zip file.
Then rename recovered-something.zip to recovered-something.fla and it should now open.
I have written a blog post concerning Unexpected File Format issue , could you please see if the updater fixes the problems for you.
Thanks and regards,
Adobe Flash Professional Team.
I am having the same problem. The zip repair solution did not work and the update doesn't work because I am using CS5 (not CS5.5).
I created my fla file yesterday - it's a simple drawing, was working on it today tried to save it and it wouldn't save - I tried saving to a different place - still wouldn't save. I closed it down and tried to reopen and have not been able to open ever since (I get the 'Unexpected File Format' error). I restarted my machine - installed the CS5 update, tried the zip repair solution.
Any other suggestions?
Hello Everyone. This is a very common problem with Flash Professional, even in the fully updated CS6. For starters use version control or create a second copy of your FLA using 'save as.' That is not a fix but a future measure for you to employ.
As for your question, I hope you tested the FLA. If you did, you will have a SWF file in the folder of your FLA. It may also show up as an HTML file when you look at it. Anyway, download SoThink decompiler from here: http://www.sothink.com/product/flashdecompiler/download.htm
Go on YouTube and find out how to use it. It is very easy.
Next, download JPEXS free decompiler from here: http://www.free-decompiler.com/flash/ .
Decomplile the SWF in a new folder and retrieve your FLA. Sothink will give you a very ugly FLA with like 40 frame layers (even if you only had three). JPEXS will retrieve your actionscript (except for timeline code which, I am sorry to say, may be lost forever).
I hope this will make it easier for you to recover your work and get back on track. I also had to learn this the hard way when I ran into the ubiquitous "Unexpected file format" error. I hope Adobe will fix this.
You can copy and paste timeline code into notepad and save it just in case as well.
Hope this helps and good luck!
Oh thank you a lot!!
I teach High School students game development basics using Adobe Flash. I have been doing so since the Macromedia days. Many of my students have gone on to pursue careers related to this instruction. Recently I have been using CS4. A few weeks ago, we upgraded to CS6. Since then, 6 students have lost 2 weeks of work due to the unexpected file format error. You have no idea how disheartening this is to a young person. I will go back to using CS4, and share this forum with my classes to show them that they are not alone. Apparently many professionals have faced the same disaster for many years.
it worked! i thought its the end of my work.. but thanks to you. but how can i copy the scenes? for example?
