11 months ago Theoretically you could have a function that runs on startup that checks for files that haven't been used for a long time (maybe like a year) and deletes them. Unless metadata is modified or something, there'd also have to be some kind of data file that keeps track of the last time each cached DAT file was used.
Or you could have a message that pops up that tells the player that they have old sounds in their Stream Radio cache with the command to clear it printed in chat.

Yes, indeed. Files are downloaded in the background via HTTP() to make the loadup faster the next time the radio plays an online file. It reduces traffic and is a good Anti-DDoS/Anti-Spam too.
It only works with files with a length (e.g. not radio streams). Only files less then 1.5h long are cached. The cache is capped at 16 GB total size and 1024 files. Each file is limited to 256 MB. Small files (HTTP requests) are even cached in memory (max 16x16 MB) as an additional de-duplication of requests. Small files (<64 KB) that could just be an HTML error page or something are never cached. Caching is only attempted when the radio does not error on playback, which means only valid sound content ends up there.
You can clear the file cache any time by deleting the cache folder or by using "cl_streamradio_cacheclear" ingame. The dat files can be any sound file and are saved as dat because of engine restrictions.
