Unfortunately, this is no recourse for this.

However, you can prevent it from happening again.

A program wrote by a Super User member for this exact thing, still works.

Disables CTRL + Z & CTRL + Y while Explorer is the active Window

I confirmed a moment ago that it works all the way up to Windows 10.

Source: Original post by Jelle Geerts

CTRL+Yis the (usual) standard "REDO", opposite, reverse action of CTRL+Z"UNDO".

If that doesn't work, try CTRL+SHIFT+Z for "UNDO" in some programs.

I just want to pay it forward here, but I worked for hours on some files, and then stupidly, hit Control-Z. They were ALL gone. I did Control-Y and Control-Shift-Z...NOTHING

I checked my Windows Recycle Bin....GONE!!

Then I had a glimmer of hope, because I am so used to it as 2nd nature, that I then realized I save my files to a cloud drive as a mapped drive (I don't want to say which one i.e. plugging a vendor), but with a wish and a hope, I checked the main repository online and in THAT Recycle Bin...ALL of the files were there. Literally brought me to tears!!

If this helps someone avoid what I just went through (up until I was able to resolve it), then it's paid forward.

Back in the day, in the old Windows XP explorer GUI, if you had the status bar visible at the bottom of Windows Explorer, you could tell what either Ctrl+Z (undo) or Ctrl+Y (redo) would do.

As I sit here, I'm trying to figure out how to see this... because I just accidentally typed Ctrl+Z (undo) with an app not in focus as well. I can solve my issue easily: a single Ctrl+Y (redo), and then a second time will make a ding claiming it's not a possible command. Undo once. Redo once. Redo twice fails. Problem solved.

You could try that.

Or perhaps there's a way to get at the data the old GUI used to show... perhaps by installing the original Windows XP explorer in some manner. Is this possible? It must be.
