Let’s have user.js file stored on C:\My Folder\user.js.

Run Compare-UserJS.bat or Compare-UserJS.ps1. After using drag and drop it looks like this:
filepath_A: “C:\My Folder\user.js”

When the path contains whitespace, quotes are automatically added. Running the script now leads to an error:
Split-Path : Cannot find drive. A drive with the name '"C' does not exist.

However, if I manually remove quotes (filepath_A: C:\My Folder\user.js) it works. When using drag and drop function there should be no further action required (like removing quotes), especially when it is mentioned as an alternative in Compare-UserJS.bat.
