Hello,
Today I was searching for mp3 songs and download from internet. When i finished that I wrongfully renamed all songs name as "music". How to get "music" files back real names of those songs?
Well... I'm unsure if there's a way you could do it right now. I'm assuming you've long closed the folder, so I guess the only thing you can do is manually rename them.
A tip for next time though: if you happen to accidentally rename files again, simply press CTRL + Z.
