Use batch to delete all contents of a folder but leave the folder

Is there a specific batch script that will delete EVERYTHING and I do mean EVERYTHING of all file types and folders with any name from inside a specific folder?

I do want to leave that folder intact.

I know i could delete the root folder then use "MD" to make another folder with same name.  I DO NOT WANT THAT.  Because of access reasons from remote server.  This will be used in a custom data csv export that will have a live connection updating every 15 secs.

Any help would be greatly appreciated.

FYI Just for reference folder is named "Test" on root of C.  (C:\Test)
