My agency has recently had the issue of pdf files that are saved into dropbox, corrupting when they open them in Adobe Reader on their iPad. The files are fine when they first download them, but after a few changes, they become corrupt and unable to open again. Therefore they lose all the information that was on that document. I have had everyone uninstall/reinstall the reader app after scouring the web for another solution. I can't decide if this is a Adobe issue, iPad issue, or a incompatibility issue with dropbox and Adobe. Anyone have any suggestions. Just let me know if you need more info.
Can you send us an example of one of these documents to email@example.com? Adobe Reader should not be corrupting any of your documents, so we would like to examine a file to try and determine if this was something that Reader for iOS caused, and if so, fix it.
I have a simular problem with Adobe Reader on iOS. We use Adobe Reader as our main PDF annotator at our school, which just went to a One-to-One program using iPads this year. Teachers are having student download PDF files from webpages using Safari on their iPads and "Open In" Readdle Docs. From here they "Open In" Adobe Reader. We use Readdle Docs as our file manager. The issue happens once students begin annotating in Adobe Reader, they save the file, when they come back to continue annotating, they get the message: File Corrupt. I am attaching two screen shots from a student iPad who is expericing this issue. The file name is 5_Themes_of_Geography: China.pdf
Suggestions? This has happened to about 25 of the 105 students using this file and Adobe Reader
I have also experienced this same problem with my IPAD3. I sent a 13 page adobe file from dropbox to the adobe reader. During the course of the day, I opened it in the reader and used the Freehand drawing tool to make notes.
On the 8th or 9th time I opened my IPAD, the same "Corrupt" message posted above popped up on my screen.
Is there any way to recover this file, or transfer it off the Ipad? As it is, I can't do anything but move it to another folder or delete it.
I have used this format a dozen times before without problems. This is the first time a file in the reader became corrupt during use, but now I'm worried it will happen again.
I gave Adobe my files, both original and corrupt versions. They are working on it now to find a fix for the October update that is supposed to come out. Just had another teacher have the same thing happened. Until we hear back from Adobe, don't know...
