2. Open a command window. By Start-%26gt;Run cmd. Do the following in cmd prompt.

3. Type the drive name where your USB is loaded. say f: . So u need to do is f: and then hit Enter.

4. Change directory to the folder that contains the files. Say files are in pics directory. so do %26quot;cd pics%26quot; and hit Enter.

5.. Now do ren *.%26lt;OS File type%26gt; *.jpg



OS File type is the extension of the file.How to change an operating system files into normal file?
no, your pictures were just hidden, the virus replicate your photos and renamed its file extension. after you scan and disinfect your usb drive, let your computer %26quot;show all files%26quot; your photos would appear but somewhat transparent.Right click and go to properties where you can uncheck the %26quot;hidden%26quot; boxHow to change an operating system files into normal file?
Oo... Strange prob...



I hope the following method works...



1.Open your pen drive.

2.Choose Tools-%26gt; Folder Options -%26gt; View Tab

3.Uncheck %26quot;Hide Extension for Known File Types%26quot;

4. Click %26quot;ok%26quot;

5. Now right click a photo and select rename

6. Rename to Photo1.jpeg ( here you are changing the file type, since the photo is captured from cam, it usually is in jpeg format)



All de best.... Hope it works for u....
