So, I came to know about this issue yesterday when I returned from school and used my laptop. All the files and folders except C Drive are hidden and there is shortcut of everything. I click on the shortcut and then I can access the file. But when I try to copy anything from lappi to USB, only shortcuts are being copied. Also, an .exe file is being created on the name of the folder and file. Third, when I tried to show all the system protected files and folders, a junk of files and folders came up on the disk. Don't really know what went wrong. Day before yesterday, I inserted my friend's USB into lappi. I think this might be the reason of this. Any help would be highly appreciated as I have to clean my lappi and don't want to loose any file whatsoever. Thanks, Steve.
