Files with .fs extension in ruby on rails application

I am using Spiceworks, an application made with Ruby on Rails. It has some files with .fs extension but i don´t know what are this files and with wich tools are generated. ¿Could someone say me something about it?

I attached one of this files.

Thank you.

This appears to be an archive file.... somewhat similar to a gzipped tar file, but not quite. It has a rather long header and starts with what I assume is a magic string: "[depot]". What follows is a VERY long and sparse header followed by a series of records consisting of a filename (with relative path), a length, and compressed data.

I pulled apart several Spiceworks file to verify these findings and they are consistent. I would post more info, but I'd rather not be in any sort of legal trouble - and would very much like Spiceworks to continue as a freely available ad-supported package - even if it is closed source.
