- Hint1: It's a scripting challenge right?
- Hint2: exFAT
- Hint3: buffer
Just share the .img file.
- Identify the file system type of the
.img: exFAT - Mount it
- See there is a folder in a folder in a folder...
- See that all folders are numbers: int (hex) -> str (chr) gives a valid ASCII value
- Retrieve the complete path and transform it to ASCII text
In order to accomplish step 5 you will need to script because the path is way too long,
so ls or general library filesystem helpers can't handle it. You have to take
a bufferized approach.
solve.sh is automating steps 1. to 5.
