OSFMount ramdisk and GetVolumePathName API call

[nuldev]

I've created a ramdisk using OSFMount 1.5.1015.0 on drive letter R:
osfmount.com -a -t vm -f D:\Ramdisk_1G.img -m R: -o rw

The Win32 API call GetVolumePathName behaves strange:
Called with "R:" as input it fails with ERROR_INVALID_FUNCTION.
Called with "R:\My Folder" as input it succeeds but returns "R:\My Folder" as result where it should be "R:".

GetVolumePathName is essential to determine the right path for calling GetVolumeInformation.

It isn't a question that has come up before and isn't something we have attempted ourselves. So we don't know the answer.
OSFMount is a free tool, so technical support is limited. But if it is a critical issue for you please contact us about paid support options.

as i know that feature only worlks if there is a Volume identifier like all "Real" Volumes have one
try GetFullPathname than you get what you want:
