It allows to overcome a bug or defect of Visual Studio Code, which is the following: when Copy Relative Path or Copy Path is done over a directory of the project, that path is copied to the clipboard with the backslashes inverted, not allowing to 'cd' to those paths in the cmd.

This extension allows to invert the bars or slashes it with just 3 clicks: 
1) paste the copied path 
2) click Replace
3) click Copy 

This saves the work of going to a Notepad, do Ctrl+F, write the original slash in the search input, the inverted one in the replace input, and click 'Apply to all'... 

I hope you find it useful, I use it almost every day ;)
