Password protect a folder

Is there a way to set a password to a text file in Windows Vista i.e. when I try to open the file, it should prompt me for the password? do I need a third party software for this? if so, any recommendations please (including free ones)?

I know, not an exact, exact duplicate, but close enough, as you would have to put in a "container" of some kind, in order to protect it.. – studiohack Apr 27 '11 at 0:26

Password protecting of folders is not supported on Windows NT (i.e XP, Vista, 7) unless you zip them. Right click a folder, then "send to > compressed folder". Now open the zip file, you will find an option under file> "add a password".

If you do not want to zip your file, you will require third party software like this one.

The ZIP encryption algorithm is so weak it's worse than nothing. (AFAIK, Windows doesn't yet support AES for ZIP archives.) – grawity Apr 26 '11 at 21:53

Try Izarc:

You can save your files in a ZIP file and add a password. The same software can be used to open the file as well.
