Answer by Bill for How can I prevent a folder from being inadvertently deleted by myself?

Yes, potentially limited by which version of Windows you have (Home versions may not have the ability to adjust ownership). Also, beware that removing your delete permissions is not a guarantee that you can't delete the folder. I've been burned multiple times.

Here is a method that is usually foolproof:

1. Create a new user
2. Assign ownership of the folder you don't want to be able to delete to this new user
3. Remove your user's access to delete the folder, make sure your user has full read/write privileges in the folder.

I've used this trick on Windows NT to Windows 7. Sometimes you have to monkey around with the settings a bit before you get it perfect.

TEST THIS ON A NEW FOLDER FIRST (including creating files and folders within the test folder!

Also: Heed the advice of "Use Backups and version control". If the files are that important, you need at least 2 copies.
