Set another file explorer for copying

[rp1231]

I want to set directory opus as the file manager for copying files instead of using windows explorer. Is that possible?

Unfortunately, WinMerge's file or folder copy uses the Windows shell (IFileOperation), and I don't think you can probably use Directory Ops instead.

That's unfortunate. I was trying to merge files with long paths and the windows file explorer doesn't support long paths..... Looks like i'll have to do the merging manually using directory opus then......

@rp1231 that's just a registry key change away:

https://learn.microsoft.com/en-us/windows/win32/fileio/naming-a-file

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem]
"LongPathsEnabled"=dword:00000001

@grovkillen I have that enabled already but the explorer.exe doesn't support long file path copying and I still get that error.

@rp1231 that's weird since I use it in my automation all the time. You mean you get the error when copying long paths outside WinMerge?

@Grovkillen yep...
