Retrieving temporary or "lost" files

Thu Mar 01, 2018 7:20 am

Good day.

Is there any way of retrieving a "lost" file?

This is what happened:

I opened a document, worked on it - but didn't save it; I didn't close Xchange Viewer
I put my laptop into sleep mode and pulled my memory stick.
When I restarted, I didn't put the memory stick back in, prior to restarting the laptop.
When I went to the (open) PDF-Xchange viewer, the altered document showed briefly (so it was there SOMEWHERE on my PC memory!) and then PDF Xchange Viewer realized that the memory stick was not in place, so it asked to REOPEN the file. I reinserted the memory stick and then hit REOPEN.
The old version of the file appeared.
The changes were gone.

Clearly there is/was a temporary copy of the altered file on the computer.

The question is: how do I access it?
Does PDF Xchange Viewer have a temporary file folder? I have searched the drive with terms like "*.temp", *.tmp*, *file name*.tmp etc - but to no avail.
Does Windows maybe store it somewhere?

I made so many changes and would really like to find that file if at all possible!!

Hello Tiger,

The Auto Recovery functionality is now available in the latest version of the PDF-XChange Editor.
You can download it from here:

There is no such a functionality in the Viewer and it won't be implemented either.

You can often successfully recover deleted files from a PC, it all depends on what has happened since the files were deleted.
When you delete files the data itself isn't deleted, just the index entry that tells the system where the data for those files is located. The area containing the deleted data is also now marked as free space so it is available for any new files to be written there instead.

If and when that happens, then it is too late to recover your deleted files so it is very, very important to not save any new files or data to the device concerned.

One of the easiest ways to see if you can recover deleted files is to try some good file recovery software like asoftech photo recovery pro, which not only recover photos, but also vidoes, pictures, documents, etc.

Cheers, Jess
