Hi everyone!! I'm new in here, and not a english speaker, so sorry for my bad english sometimes... Here's what just happened to me, and makes me want to punch some walls (litterally..): I always used Windows Media Player 10, for audio and movies, but I just get some audio files with the extension "m4a", wich I searched to know what these were, and then discovered that the Real Player could read them. Then I downloaded the Real Player 10, and installed, all fine 'till now... In the instalation, when it was asking if Real Player would be the standard program to run the audio and video files, I choose "no", and when I had to choose the files that it would open, I did'n selected neither mp3 or mpeg, or anyone of this kind (actually I didn't selected anyone). After the instalation is completed, I run the "m4a" files, and it was alright, they played without any problems. I stopped the execution of the files, and moved these files from the folder they were, and putted with the others audio files, and all of them were still there... then I cosed the Windows Explorer and the Real Player. But when I opened the Windows Explorer again, I realized that ALMOST MY ENTIRE FOLDER OF USELESS LITTLE THINGS (like all my mp3, videos, movies, pictures, texts, and all sort of things) HAVE JUST DISAPPEARED!!!!! This folder now just shows 1 video and some mp3, that were apparently configured to play in Real Player (when their icon is of the RP, not the Windows Media Player)!!!! I then uninstalled the Real Player, and these files becomes to execute directly in the Media Player, without any problems... but all my other files are gone!!!!!!! I'm thinking thats it's extremely weird because I'm not talking about a few MegaBytes... I'm talking about 75 GigaBytes of files!!!!!! They can't just dissapeared like this, in a blink and without any warning, can they?!?!?!?! I wanna know if they are somehow still in my pc, but can't be accesed or recognized, and if it's possible to recover them...... or if I really have lost them!!!!!! (nooooooooo..........) After all, it's accusing that I have all that 75Gb free in my hard disk..... And I wanna know if the real Player is that complicated and bad to the system, 'cause thats what I'm thinking of it right now... Sorry if the text is too long.... but I'm really desperate!!!! Tanks for any help or explanations!!!!!!
