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.
Fast file syncing based on BitTorrent. Very easy to use and very fast.
Drag and Drop
Perfect for small files. Drag a file on top of Paperspace window and it will upload to your desktop.
