I am helping my uncle to improve his computers. He told Deleted items in Mapped Network Drive will not go to Recycle bin. If he deleted an item in a mapped network drive, he will not able to recover that in his Recycle bin. Today, this is the frist times, I realized that is a problem. I believe network drive is not for the user to do the daily operations, that is for backup and sharing the documents. You should not move those files around, so that is rare to delete the file.
