Folder change listener and backup

[Tygara_191]

A bit of background:
I was working in my htdocs folder, building websites. So what happened is I was in:

"htdocs/project1/randomsubfolder" and pressed ctrl+z in file explorer, that resulted in the undo of changes I had done the previous day in the folder "htdocs/project2/"

So I ended up infuriated with 2 days of work from the folder "htdocs/project2/" gone. Woosh!

 

Questions:

       - How do I make the windows explorer undo feature request permission to delete and/or modify files.

       - I want some advice on software (preferably free) that will keep a changelog of that folder for me. So next time something similar happens I can just check the changelog and return a given file to a point I prefer.

I think you are looking for version control. Git is popular. TortoiseSVN is useful on windows
