There are a number of ways to get files into Paperspace. Depending on the size of files and how often you plan to modify them you have a number of different options. For most users, we recommend BTSync (see below). If you have a recommendation please let us know and we will happily include it on this list.
Drag and Drop
Perfect for small files. Drag a file on top of Paperspace window and it will upload to your virtual machine's desktop.
Note: Only Windows support at this time. Not recommended for large files (> 2Gb)
Fast file syncing based on BitTorrent. Very easy to use and very fast.
