Yeah, like that.

So to be 100% sure: You're in that folder. The mouse cursor is not over any file at all. CTRL+A => XY "freezes" for about 25 seconds? It can't be the number of files you're selecting because I've tried it with 50.000 a minute ago. Add the "Type Stats and Filter" button to the too...

So the "XY64.exe" is responsible for holding the lock... It blocks the preview handler so that no other process has access anymore, e.g. if you're having the File Explorer preview window open and view e.g. 1.pdf, switch to the same file in XY, the preview of File Explorer "gets lost&q...

It's about the 32-bit context menu chocking when you click on white after selecting all files. That it does work flawlessly when you invoke the context menu on that folder alone... The problem is: I don't see any relevant settings in your .ini that I could probably blame for doing this... Configurat...

Even in a fresh instance?

Because I can't confirm that observation...

XY v25.40.0300, fresh

I'm creating a copy of the 1.pdf in XY, preview it in XY, change to File Explorer, select the same file and delete it...

Show the content of both your work and home tag.dat files (after the "Data:" line)
The first 5 lines should be sufficient

You're using the 32-bit context menu, so: How many items are in the original folder (not when split up into two) When you right click on the selection, is the click above a file name? If yes, does it make a difference if it's a small or a large file (1 MB vs. 10 GB)? Please set these options and try...

Exactly
