I would install Search Everything and do a search for the file name. This will let you know if the file exists on your computer and the exact location.

Search Everything is a small, free search tool which searches all files/folders on your whole computer quickly and easily.

I found the solution.
SnagIt will rename the file before move it from
c:\Users\<username>\AppData\Local\TechSmith\Snagit
to the Recycle Bin
So when I restore the file from the Recycle Bin, it will restore to
C:\Users\<Username>\Documents\Snagit

I tested it myself.<br />Thank you for your help!

I use SnagIt all the time, and I pointed you directly to the correct subfolder in my post #36897396 . I think I found your file for you. .... Thinkapds_User

Yes, you're right.
I would accept that. It would be better if you can tell me it get renamed.
I would give B for that answer. Thank you!

It would be great if you can tell me it get renamed by SnagIt before move the file from SnagIt Library to the Recycle Bin.

Thank you.

I opened Snagit and captured a bit here. As I recalled, it does not attempt to make a name in Snagit Editor until I do a Save As. Then it uses a time stamp as the date. See below. I think the use of a time stamp as the filename is at the bottom of why it gets renamed (the time changes).

 
I instinctively give my files real names (I have a couple of hundred such files for use here at E-E). Time stamps would quickly be hard to use. Now when I save as a real name, it saves always in Documents\Snagit, never in the temp folder. I looked here (C:\Users\thinkpads_user\AppData\Local\TechSmith\Snagit\DataStore) and here (C:\Users\thinkpads_user\AppData\Local\TechSmith\Snagit) and there are a couple of dozen in each folder - all fairly recent.

When I delete my real files, a restore from the recycle bin will always bring them back to Documents\Snagit with the same name. I think it is the temporary files you are deleting getting a new name.

So my suggestion is to save your images in the Documents\Snagit folder and then I think your problems will go away.
