I did everything. I tried to manually change the extentions back to .jpg, .mp3, etc, but the files still don't work. Please help I know there is a way to get the files back working again. I have important work files that were changed to .losers extention. Various video, music and other files. Please help. I had to back up the .losers versions of the files to external hard drive and did a clean install of Windows now I'm trying to change back the .losers files on my external hard drive. Thank you
