What You Are Seeing?

When trying to install a package that exists in the root of a drive (local or a remote share, mounted as a drive) with the -s . command line option, when the shell is in that directory, you get the error:

Source '.' is unable to be parsed

For example:

PS Y:\> ls

    Directory: Y:\

This also happens with the local C: drive:

If you specify the drive specifically, it works:

PS Y:\> ls

    Directory: Y:\

Note that I originally got this with the unzip package and then used zoomit as a second test.

What is Expected?

The command line option -s . work when the Chocolatey CLI command is run from the root of a drive.

How Did You Get This To Happen?

1. Downloaded the Zoomit package, version 4.50.0.20160210 from Chocolatey Community Repository to the root of C:\ (note I had this package version here, so I used that, which is why it is not the latest).
2. Opened a PowerShell Administrator session from the Windows 11 included Windows Terminal.
3. Ran cd c:\
4. Ran choco install zoomit -s .
5. Saw the error message Source '.' is unable to be parsed.
