Forgotten Password with PowerPoint

I think I know the sad answer to this, but I made a PowerPoint presentation and password protected it.  I have no idea what password I used. Any way to get the presentation back?  Windows, recent version of PowerPoint.

Thnx,

Cipriano

Is it an open password or a modify password?
Jamie GarrochSenior Technical Consultant at BrightCarbonCommented:
If you're using the newer XML formats, AFAIK, the only way to "recover" a password is to use a brute force attack which basically tries millions of combinations of characters in an effort to "guess" the password. There are a couple of tools around that do this for you and this is one I found just by Googling so I'm not saying it will work, just that there is software out there that claims to work:

I remember, I made it something "simple" because I was tired of long paswords with special characters, up and lower case, etc...but I don't remember what the simple password was
Echo_SCommented:
Yeah, then Jamie's right -- brute force is the only way. I did a quick test here by unzipping the file, and the password is apparently in there but it's been hashed so it's not listed in the text. (I'm sure someone can reverse engineer the hash somehow, but I don't have hacker-level skills with hash tables and passwords. :-) )

Most, if not all, of the newer versions of PowerPoint ignore modify passwords in at least some situations. (Sorry, it's been a while so I can't recall the specifics.) But open passwords are more robust. Since you used something "simple," that password recovery generator Jamie pointed to might work.

I was able to recover the password using the recoverlostpassword application.  I knew it was easy, so 4 characters or less, no special characters, no capitals and yes....it found it.  Thanks so much for you help.
