Evernote will back it up and make it available on any computer or device you use, wherever you are - kinda simple file sharing.
- If you use Evernote on Mac just drag a file into a note or onto the Evernote dock icon. Alternatively, you use the
File-> Attach File menu option.
- Windows: Drag a file in a note or right click in a note and choose the File option.
- Evernote Web: Edit a note, then drag file onto the note header or click the paperclip icon.
