Re[2]: Maximum volume label length

I would guess that this is hard coded in Explorer since Windows 95,
where volume name was 8+3 on FAT.

As for NTFS: Explorer has been known to check for file system
by name, so I’d say there is like:

if(fsName == “NTFS”)
nMaxVolumeLabel = 32;
else
nMaxVolumeLabel = 8;

(even tho FAT volume name has always been 11, not 8, at least in DOS
times).

I don’t think you can change that in your driver.

Yes this is right, the same issue has come up for other features in the
filesystem so some fs driver writers has considered letting their fs
return the name ntfs because to allow the user to use the advanced
features they support.

However you should file a bug report for Explorer!

Thanks for the responses. That sounds strange anyway!. You may be right, I should rather file a bug for Explorer!!

Probably the Windows shell has hardcoded check for “NTFS” literal.

Sounds like a bug in explorer.
