How to edit information in an .MSH file without hex editing?

[Bugmenot2017]

Hi, what the title says, what I really want is to change the .TGA and .ODF (Cloth) file names to something longer, because hex editing is not cool.

I must say that I have found ways to do it with programs, but with certain bugs, I mainly want to do this to organize.

Any ideas?

P.S.: If I find out how to do it without errors, I'll edit the topic.

EDIT: As I said, I'll share my solution, the best solution is "SchMEe" from "tirpider", but I can't edit the .ODF name of the .MSH file.

Something is something, I have also learned to put parts of one unit in another, like backpacks (directly in the model, not as a complement).

If someone wants to search and learn how to use this program, they can do it on this site.
