Unable to run tool with files on other disks

[Dragoonstorm1]

Getting the error: The directory name is invalid
Upon running the tool on any media file on drives other than installed drive (in my case installed on C:\ Drive)
Same issue even if method of running is via shell options or CMD with Admin Privileges with full path to BAT and path to file, and quotes.
Issue resolves when I move media files to C:\ Drive.

And failed reads make it auto assume SDR (which is a wrong fallback I guess?)

For example, output when running FileInfo

The directory name is invalid.

Analysing File. Please wait...

The filename, directory name, or volume label syntax is incorrect.
FINDSTR: Cannot open I:\Media\PasswordChars:~61,16v3G_TMP\Info.txt

Also extremely strangely, when running things like Demuxer, it fails to read the file and YET it reads the framecount and resolution.

Demuxer output:

FINDSTR: Cannot open I:\Media\PasswordChars:~9,1diEn_TMP\Info.txt
