I have a file of my own that I have encrypted using Coder-Abi. Now, I can just remember part of this password. So, would it be possible (much easier) for me to crack it knowing only part of it? I can remember around 20 of them. The files are pictures, excel and word files.

If there's any software (mainly freeware), please let me know.

Beware you may have to write your own script to do the job. – rath Jan 2 '14 at 15:10

Your best bet is brute force. If you know a significant proportion of the original password, (e.g., 13 characters out of 16), it wouldn't be too time consuming for a script to attempt all other possible combinations for the remaining characters.
