Sandpaper v1.0 is an FTP client and server for TI graphing calculators, with two major purposes. The first is to let you transfer files between two (or more!) calculators, even if you're not close enough for a link cable. You can connect over CALCnet or globalCALCnet, connect to a remote calculator, browse the programs, groups, pictures, appvars, matrices, lists, GDBs, and strings, and send files to and from the remote calculator. Its second purpose is to let you download (or potentially back up) files directly from and to the internet. A bridge for ticalc.org is complete, meaning you can browse the ticalc.org file archives directly on your calculator, view the contents of zip files and readmes, and then download calculator files directly from those zips onto your calculator.
