Pretty much so.
Look around for various "ripper" programs. They can have functions for extracting/converting data from these formats.
Take note that some of the files you're trying to rip might (but don't
have to) be in-house formats, which may complicate things.
Regarding FLC, check this:

I'll run the rippers I have on the files, will see what results I'll get.
