Hello,
A noob question (but I want to understand its meaning and not just do next to ignore it.)
When opening a new file in IDA I have the following question regarding the file:
Portable executable for 80386 (PE) [pe.ldw] / MS-dos executable [exe] [dos.ldw] / Binary file
1. What are the major differences between those?
2. Why IDA asks me to supply an answer?
3. What can happen/go wrong if I choose "wrong" pick?
4. How can I know what I need to pick when opening a file?
Thanks.
