I need to know how tar, dump, cpio works. what is the algorithm behind all these program. How does tar traverse a file system tree, etc. Where can I get the details?
Thanks
If you want to know in detail how they work, you can download the source code of GNU tar, GNU cpio and ext2 dump.
If you have specific, more high-level question about one of them, you can ask a new question about that.

I am wanting to learn the ropes with 7z. This isn't working...I followed 7z --help:
7z x -r beans.7z personal.php
I want to make a .7z file called "beans.7z" and what contains the file "personal.php"
The error I get is:
Error:
there is no such archive
Here is the correct command for what you want to do:
7z a beans.7z personal.php

I want to monitor a process in windows to check what actions it performs on a particular file including renaming it, or encrypt it. I want to generate events for these actions.
its easier to monitor the file than the process. Take a look at FileSystemWatcher class. http://msdn.microsoft.com/en-us/library/system.io.filesystemwatcher.aspx

Does Boost have a support for MD5 checksum calculation?
Is yes, how to you use or can you provide some tutorial?
Thank you.
No, it doesn't have. Consider using OpenSSL, Crypto++, and so on.

I have a binary-only copy of an application written in Delphi 7; as part of its execution, it writes some data into a text file (not in plain text).
Is it possible to extract the data from the file if I know part of the input data and have a copy of this file? (What if it's encrypted?) I have no idea about the structure of the mentioned file.
And no, I don't have source code for the application -- I think that's obvious.
Yes it's possible, you would have to reverse engineer this application first (IDA, HIEW) and/or debug it while it stores the data to the file, contact me if you need more help.
