Summary0000530: Magic file to detect EldOS Corporation SolidFS (.st) files.
DescriptionThere used to be an EldOS Corporation, which according to the following link (https://www.componentsource.com/brand/eldos) used to promote "development of security, communication and data storage software components".

Their website now redirects to a certain "Callback company", who appear to have some products very similar to those produced by Eldos.
The fact is that EldOS used to provide a file system called "SolidFS (or SolFS)". All points to EldOS corporation being now dead, but files created by their SolidFS software can still be found, especially in games from the (now also dead) South Korean company "Softnyx". They used SolidFS to store game assets in both encrypted and unencrypted formats, although with the .XFS extension.

So, I wrote a basic magic file to detect EldoS SolFS files and their respective page size. There is more info that could be added in the future (like the ability to detect whether the file is encrypted or not), but that's beyond my skills.
Having file detect these would be nice for people who work on preserving the games made by softnyx (There's a bunch of people that forms a community who does that). The .xfs extension was used by softnyx in different types of files, one of them being SolFS containers, which when created by the official tool SolidFS explorer have the have the .st extension.

So I'm attaching a text file with the data necessary to create a magic file that detects SolFS containers as well as the page size.
