How to analyze binary file?

Question

I have a binary file. I don\'t know how it\'s formatted, I only know it comes from a delphi code.

Does it exist any way to analyze a binary file?

Does it exist

Answer 1

For my hobby project I had to reverse engineer some old game files. My approaches were:

• Have a good hex editor.
• Look for readable words in the binary file. Note how their distribution is. If the distance between them is constant you know it is a listing.
• Look for 2-3 consequent zeros. Might indicate an int32 value.
• Some dwords might be pointers into the file.
• Try to identify reoccurring patterns in the file.
• Seeing lots of C0-CF might indicate RLE compressed data.
