Look at the situation when you download, there are five sources and dozens of sources. When others download, the files on your hard disk will become source files and be uploaded. If you don't want this, God will shut it down.

Setting the disk cache has an effect on buffering playback, but has no effect on uploading.

The trick to reducing uploads is:

Download the file, move it to another disk, and try to change the file name, for example:

Mulberry leaf, change it to leaf, just don't let it know the name of the music file you downloaded!
