Windows systems have a high degree of coupling.

Today, I am searching for MP3 files downloaded several days ago in Windows Media Player, but I haven't searched for them for half a day. Because folder monitoring is set up, it should be automatically added. I am wondering if you cannot manually add it. If you do not add it to the media library, there is no useful prompt information. When I was thinking about re-installing WMP, I suddenly remembered that the IE history could not be used, because I used to change the temporary ie folder to the partition of the SCSI hard disk, later, I thought that the SCSI hard disk was too noisy and I had never been able to use it since then, and I did not care about it. Does that have something to do with it? So I changed the temporary ie folder back to the default location. It was a faint, and WMP went back to normal. All this evil windows has something to do with IE.
