• Prevent setting the cache directory to a non-empty directory. Or..
• Issue a strongly worded popup confirmation if the system detects the cache directory is being changed to a non-empty directory

A quick way of addressing this would just be to prefix any of the cache files with a certain name "jfCache_" or something and then only delete files with that prefix.  Right now i see a file in my cache called "3fcc023749b2f856cbafe428b5f6bc830.ts", so let's just make it "jfCache_3fcc023749b2f856cbafe428b5f6bc830.ts"
