Pattern for mass file extension change

[knightsofni]

Hi,

I have a whole bunch of files with extension .MP4
Would like to make these extensions lower case .mp4

I'm trying *.MP4=*.mp4 - but that doesn't seem the appropriate syntax.

How is this achieved in XYplorer?

Select the files which you want to have a lower case .mp4 extension, right click them, context menu - Rename Special - Set Extension...

Enter:
mp4

in that window, hit OK

Thanks for your reply. I don't seem to have a context menu though.
Which is weird because I do have it on another computer

No context menu at all or only the "Rename Special" is missing from it?

Menu - Tools - Configuration... - General - Menus, Mouse, Safety - Button "File List...":
[x] Rename Special

[knightsofni]

That box is already ticked. There are no xyplorer specific options at all the in the context menu. Just the standard ones that are also in classic explorer.

Configuration > Shell Integration > 64-bit Windows > Show the 64-bit context menu. Uncheck that.

Got it now, thanks!
