While I was working on PDF files, all PDF files were not responding. Ctrl/Alt/Del - programs other than Acrobat Pro 9 were OK - Ended task for all PDF files.
After I opened those PDF files, those could not be recovered.
1) Is there any way to recover PDF files when the file is corrupted?
2) Does anyone suggest a utility program effective in recovering corrupted PDF files?
3) What are the preventive cautions or actions to do before actually corrupted? (Auto Save is set to every 1 minute)
I heavily rely on PDF files for paperless documents. Please share your resources with me regarding this kind of problems. Thank you.
Google for "pdf data recovery" and you'll find several products that might be able to help, but none will guarantee to work on a particular file as it depends which areas of data are damaged.
Auto-save is not much good if the corruption has been written to the original copy - the only reliable solution is to keep backups of your files / folders / disks, for example by mirroring them each night onto a different (external) HDD. That way you're protected against anything, including your computer exploding or being stolen, and you'll only ever lose 24 hours of changes. All decent backup software can be set to run scheduled mirrors, some are free, so you just need a USB or networked HDD.
