This type of path isn't officially supported. It depends on whether Windows returns any errors when trying to use these paths.

But why here on Vista 32-bit it works with %COMMANDER_EXE% /L=\\?\Volume{GUID_by_mountvol}\, and doesn't work with internal cd command? Maybe the reason is a different error handling for /L parameter and internal cd command?

Internal cd command calls SetCurrentDirectory, which apparently fails for these paths.

In modern versions of Total Commander, the option OldStyleDir=0 is used by default which tells TC to use FindFirstFile to check for dir existence, but then it means this parameter is not applied to internal cd command?

Anyway, shouldn't even cd use FindFirstFile if last path character is not a slash (/) or backslash (\)?
I tried cd \\?\Volume{GUID_by_mountvol} (without last backslash), but it still doesn't work.

Try a Free Tool called USBDLM. This is a free portable program that can control drive letters by almost any criteria ie Volume Label=?, Device ID=?, Device Serial Number=? ... some 15+ options

[DriveLetters]
VolumeLabel=Backup?
Letter=U

This would fit for a VolumeLabels Backup1, Backup2 etc.

USBDLM works with XP, Vista, Windows 7, 8, 8.1, 10 and all the Windows Server versions. The x64 version works on x64 editions of Windows only.

I use it on Win7 and Win10 - works like a charm
