Homebrew [Help] Getting the ExeFS Extracted With ctrtool

[jluponeage]

Hello everyone!

I know I must've figured this out earlier, but I can't remember how to do it and I got a new computer because my old one broke (so, basically, I lost all of my files).

Anyway, I know which commands to use (-x, --intype=exefs, --exefs=Desktop\exefs.bin, --decompresscode, and --exefsdir=Desktop\Exefs), and I don't know why, but ctrtool is giving me an error when I try to extract my exefs. It says "error: could not open input file". This is exactly what I put in:

C:\"Program Files (x86)"\HackingToolkit3DS\ctrtool -x --intype=exefs --exefs=Desktop\exefs.bin --exefsdir=Desktop\Exefs --decompresscode Desktop\exefs.bin

ctrtool worked for extracting my RomFS, by the way. But I can't remember what I did for that either because it was a while ago. I am getting pretty frustrated at this.

So, my question: How do I use ctrtool to extract the contents of my ExeFS?

I believe the files have to be in the same folder. You could try looking at this. Put your ctrtool in the same folder as your exefs.

I mostly use 3dstool instead as I find it works better.

3dstool.exe -xvtf exefs DecryptedExeFS.bin --exefs-dir ExtractedExeFS --header ExeFS.Header

Thanks for your guys' replies. Unfortunately, neither worked I have actually already looked at the website you suggested. For 3dstool I just tried the following code:

3dstool -xvtf exefs [new ExeFS path] --exefs-dir [encrypted ExeFS path] --header ExeFS.Header

Adjust your "Desktop" paths to be absolute paths.

There's also my tool, which comes with a GUI.

Thanks, but it's not what I'm looking for. You need a pre-built ROM for that tool, and I don't have one.

Alright, I found some code (based on https://gbatemp.net/threads/how-to-decrypt-unpack-exefs-to-get-3ds-banner-file.386811/ first post by mid-kid)

(ctrtool path) -x --exefsdir=(path where you wan to save to) -t exefs --decompresscode exefs.bin

This is exactly what I was looking for. It extracted all of the files I needed. Thanks for all your help guys!
