I need some help and advice here. I am privately learning on how to reverse engineer our teachers custom file archive file that have other files stored inside of them. for school project.

But, I am kinda lost on where I need to start with the file. What do I look for in the file after loading it into ida-pro To, be able to create my own self extracting Tool for my project.

The File format is .crackme that has been compressed with files inside of it from our teacher at school but when I double click on the file it says the file is "archive either unknown format or damaged".

So, yeah the file extension he gave us is not any known on the web he created his own extension for us to crack it and make an extractor tool to get all the data from the archive his extension name is ".crackme" so yeah.

Any Advice, here any help to is much appreciated by me.
