Reset Picasa2/3 Hidden Folder Password

So I had a hidden folder in Picasa that I didn't remember the password for, and I found an article in the Picasa help pages that said you could reset the passwords on the folder by deleting C:\Documents and Settings\\Local Settings\Application Data\Google\Picasa2\db3\catdata_info.pmp.

I only had a single passworded folder, so that probably simplified things; if you look in that file, you might see a 32-character long string with random looking numbers and letters. This is an MD5 hash of the current password. You can change this if you want (I did when testing this using a quick MD5-er at http://pajhome.org.uk/crypt/md5/). I also wanted to know what my old password was, so I found an MD5 brute-forcer and got it in a fairly small amount of time (since I was pretty sure it wasn't a long password).

Kind of random, yeah.
