Not A Supported File Format

Aug 20, 2012 6:37 PM

I built a site and now when I go to open it I get the error message that it is "Not a supported file format" but I just finished it. Now I can't get into the site I spent hours working on. I have not upgraded the program. What do I do now?

    Please send us a copy of your file at and include a link to this thread. If it's too big for e-mail (>20 mb) you could use a service like SendThisFile, Adobe SendNow or WeTransfer.

    I don't have good news. This file is corrupt at a low level within the underlying SQLite database Muse uses. I don't have a way to repair this file. I'm very sorry.


    It would be helpful to know more about your environment in order to identify a pattern if/when we see this with other files. To date the other reports of this error during open have primarily been caused by files that showed clear signs of having been truncated due to incomplete file transfers or having been saved to removable media that was subsequently removed without being ejected. Your file doesn't show this type of damage. Rather it's the correct size, but contains blocks with incorrect data. While that could be caused by media failure, it seems more likely to be a bug somewhere in Muse.


    Are you working on Mac or Windows? What OS version?


    Was there anything unusual the last time the site was saved? Was the last save a Save or Save As?


    Was the file saved on the boot drive, an external drive, a network drive, removable media, other?


    Was the file saved in a DropBox folder? (If so, DropBox keeps a backup of previous saved versions.)

    Unfortunately, there's no way to go from the exported HTML/CSS, JavaScript and images back to a .muse file.


    It's unclear from your comments whether you were opening and working on the .muse file while it was on a thumb drive or you just did a Save As to a thumb drive at some point?


    I'd definitely recommend against working directly on files stored on thumbdrives when in any program. Removing a thumbdrive without first ejecting in the OS or having it temporarily jarred loose can result in truncated or otherwise corrupt files. It's much safer and provides better performance in whatever program you're working in to copy files to your hard drive and work on them there then copy them back to the thumbdrive when you're done.


    The answers to my questions in your reply failed to come through in the support forum. The forum software is not as good as it might be at handling e-mail replies.  If you could send the answers to me directly at or use the in-browser reply feature in the forum that should ensure your response makes it to me intact. Thanks.
