Amit sinha asks:
I have forgetten my zip file password which is almost 21 characters long and consists of lower case and upper case letters with numbers and special characters. Guessing it is out of the question. Is there any way to recover my files?

Bruteforcing too, is out of the question. What application did you use to pack it? You could try searching for a vulnerability in the packing scheme or encryption implementation. You can search for these vulnerabilities at exploit-db and security focus, which if you’re using older compression software the vulnerability is likely still available.

It would take About 65 trillion years to bruteforce even a dictionary phrase, whereby the bruteforcer contained all the keys mentioned in the password. If it was a completely arbituary password as Amit mentioned, there is about 0.00000000001% chance of it being cracked by a traditional dictionary based bruteforce attack.
That’s why I added to look for the data, or recover the deleted data using data recovery program instead of trying to remove the password.
The easiest option(if it works)
Bruteforce using Amazon EC2 Services it will cost you a little bit but it can crack just about anything in an hour
An easy solution to solve it; Firstly you need this :
1) Install WinRAR latest version, free or paid doesn’t matter.
2) On your computer, find your zip / rar file that one you lost the password.
3) Highlight the file, right click on it. Click on ‘Delete’ or press ‘Delete’ button on your keyboard.4) Then click ‘OK’ if it asking for permanently delete.
5) Problem solved.
So where does needing WinRar come in?
Does that get him his files back?
