[Request] Extracting only part of a 3ds file using ctrtool

[kriNon]

Hey,
I'd like to only extract one of the files in my romfs. I am currently using the command ctrtool.exe --listromfs --romfsdir=romfs sun.3ds. I am only interested in the file named 4 in the directory romfs\a\0\9 . Is it possible to only extract this file without extracting the entire filesystem?
I am writing a script that uses ctrtool and the performance of the script is important, and so extracting the entire filesystem and then deleting what isn't needed would not be ideal.

Thanks

ctrtool doesn't support extracting single files. Not sure if there is any other tool which supports this.

Any chance for a feature request? Would be really useful for what I'm working on.

It’s in development, along with a complete refactor. There’s no ETA on the release date yet.

If it helps, there is a ROM mounting tool called ninfs. May not be as performant as extracting files directly, but it'd be quicker than extracting the whole ROM.
