If you have an Apple Time Capsule device and want to share files from that to the stick, you need to keep several things in mind.
 

1) You need to have the latest 1.3x software on the stick to mount a folder on the Apple Time Capsule
 

2) The stick currently only mounts the Guest folder on the Time Capsule, please enable the Time Capsule 'Disk' Tab to enable file sharing, and also to enable the guest account to have at least read only permissions
 

3) Restart the Time Capsule (by clicking Update) and wait about 5 mins.
 

4) Click on the add/remove button on the WMS management page and add the folder DATA (or whatever you may have renamed it to be)

If you have many files and folders in a different folder on the time capsule, you will need to move or copy the files into the DATA guest folder and they will show up on the stick
