It detects some worms..thus by cleaning them all my files disappears. But when I right click on my pendrive icon n saw its properties it seems that my files r still zer but r hidden. I tried every steps that show up on z internet but it was in vain. I just try something simple n it works perfectly.that's y I wanna share with u friendz..
1. Ensure that win rar is installed on ur pc/laptop.
2. Insert ur pendrive and right click on ur pendrive icon, u'll c "Add to Archive(winrar)".
3.Click on Add to Archive and click OK.
4. When z Archive Process is completed, double click on z Archive folder, u'll c all ur recovered files zat were hidden on ur pendrive.
5. Next u create a New Folder on ur desktop, click and drag each files zat u wish to recover back from ur Archive winrar folder to ur New folder located on ur desktop. That's it.
Hope zis help u guyzz...:-)
