Looks like we need to strip the glob prefix if we detect we have a drive letter.

@mitchell-codecov do you remember if we fixed this?

[mitchell-codecov]

Not to my knowledge. Something we did learn was that the library we use for globbing has Windows-oriented capabilities which may be of interest.

@joseph-sentry Please take a look here if we still need to do this and work with @dana-yaish for a solution.
