2. From your Operating Systems File Manager:
ThePhotoStick stores your photo and video files on the USB stick in the directory path: <ThePhotoStick drive>\My_Files\<computer name>.
For Windows computers, for example, if you plug ThePhotoStick into a Windows computer with a computer name of mphillips1, and Windows assigns the drive letter F: to ThePhotoStick, the path to files backed up to it would be F:\My_Files\mphillips1\.
For Mac computers, ThePhotoStick is always mounted on the path /Volumes/PHOTOSTICK. So, if you plug ThePhotoStick into a Mac computer with a computer name of phillips-mac, the path to files backed up to ThePhotoStick would be /Volumes/PHOTOSTICK/My_Files/phillips-mac.
