Not in any significant way. The decompressor could be changed to require you to feed the files into it in the correct order or expect some other sorting.

What you're saying is like saying that you encoded info in filenames because decompress.sh expects a file "compressed.dat" to exist. It's not describing any meaningful part of the scheme.

The filenames contain information that you need in some way for the scheme to work.

You are combining different parts and inserting a missing byte every time you combine the files. You need to combine the parts in the correct order, and the order is part of the information that makes this work.

If the ordering isn't coming from filenames, it needs to come from somewhere else.
