Recycler folder in c drive

[Imtiyaz]

I have a folder called recycler in C drive. It has about 4 GB of files in it. When i click on it it shows nothing as it is empty. I don't know anything about this folder. What is it? Virus or malware? Anyone have any idea?

All suggestions are welcome.

When you delete a file in Windows Explorer it's not really deleted (usually). Instead the file is moved to something called the Recycle Bin.
The Recycle Bin takes advantage of the speed of same-drive moves by actually implementing a container for the Recycle Bin on every drive. So while you might see only one Recycle Bin icon on your desktop or in Windows Explorer, you're likely to find a hidden folder called RECYCLER in the root of your NTFS formatted drives. (Apparently it's called RECYCLED on FAT formatted drives.) When a file is deleted in Windows Explorer it's moved to the RECYCLER folder on the same drive.

The Recycler folder is used by Windows' Recycle Bin. You can delete it, but it will come back if you send files on that hard drive to the recycle bin. There will probably also be a "System Volume Information" folder that is generated by Windows.

These are the hidden folders of the Windows operating system not a virus. Go to My Computer =>Tools =>Folder Options =>View => and put a check mark in front of "Hide Protected Operating System Files(Recommended)" and click OK
now you won't see these hidden folders.
