Max Worker All workers running on a different thread. The optimal performance depends on your device.
File streaming API limit (Megabytes) Download files directly on your computer. If the size of the file reaches this limit (megabyte), it will use the streaming technology instead of cache. Currently only the latest Chrome, Edge on desktop support this feature. See more about this api and support: FileSystemWritableFileStream
Store downloaded file in cache (seconds) Downloaded files which use cache can be held for a short time and then be downloaded instantly again. Useful if you accidentally deny or cancel the file after the download process.
Thumbnail cache Set the limit for thumbnail elements in the cache. A thumbnail is around 2KB of data, so keeping 5000 in memory is only around 10MBs.
