I am looking for a solution to minimize the amount of space used by JPGs on our company's file servers. Due to the nature of our business we have GBs of pictures that I want to limit to a single drive/folder. What I would like to do is purchase an inexpensive USB drive, attach to a Windows server, assign a drive mapping via login script, and then set up a top level folder on it to only accept JPGs to avoid any other file types being place there as this entire drive would be excluded from backup. I believe this can be done via Sharepoint, but I have one Sharepoint enviornment and 50 locations, so I dont want to push the data over the WAN, it needs to remain on the local Windows file servers. What are my options?
