Toolbox isn't in the habit of throwing away files, so I'm sure your data is there somewhere. Have you tried the
Search feature of the Windows Explorer or whichever
browser you are using? (Toolbox doesn't move files, either, but it can be in a different place than you expect.)
As you've discovered, Toolbox doesn't keep a Most Recently Closed list and you aren't the first to be frustrated by that. I am Toolbox Support and will gladly get online with you to make suggestions for searching if you'd like. I'm at Toolbox @
sil.org (no spaces, of course). Contact me there if you are interested.
