I just downloaded some new music and the next day most of the songs vanished without a trace! Plus i dont know what happened but media player put duplicate songs for every album in my library! Why might it do this?
Maybe you copy the file of the music and Windows Media Player think it as a new music file.
You might be infected by a virus. Have you checked if the same didn't happened to your other files??
Go into the options section of windows media player choose Library section and making sure that Delete Files From Computer When Deleted From Library is not selected.
perhaps cleaning tools causing this, just ask them not to scan windows media player
if you want you can try to rebuild the Media Library:
a) Shutdown windows media player.
b) Stop the media sharing service.
c) Go to Start; type Services.msc
d) Right-click on the “Windows Media Player Network Sharing Service” and select Stop.
e) Navigate to “c:\Users\”your username”\AppData\Local\Microsoft\Media Player.
f) Now delete the files named CurrentDatabase_***.wmdb and LocalMLS_*.wmdb.
g) Start the media sharing service.
h) Start Windows Media Player to build up your library again.
show hidden files
perhpas your songs are hidden somehow.
This is right. I used to do this (and some other tricks) every now and then to maintain my library. WMP is able to cause bizarre catasthrope anytime it wants, in addition of making hidden cover art files even though the album has the cover art intact already. At the end it's too much headache to keep up with its quirk and I ditch WMP, opting for third party music management software. You can try one from MUO rewards.
nice replay thanks for useful information
use TuneUp from MUO rewards
it removes duplicates
It might do this because it is Microsoft's software. What version of Windows and Media Player are you using?
