Hello,
My samsung S2 Portable 3 640GB external hard disk is showing the following error when I try to open a folder: "Windows cannot find 'G:\RECYCLER\e621ca05.exe'. Make sure you typed the name correctly, and then try again.
Please help me to solve the above mentioned issue as I have important files in my external hard disk. Thank you.
