You must have already set up a cloud account to use this functionality in Documents To Go.  To set up a free account, visit the supported cloud services’ respective websites.

To setup a cloud account in Documents To Go Premium, please follow these steps:

1. Open Documents To Go on your iPhone/iPad/iPod touch.
2. Tap the Cloud tab from the main screen tool bar.
3. In the next window select the cloud service you wish to setup and tap Add Account. You should then follow the cloud account’s sign in procedure. Generally, you will need to enter your email address and password that you used to set up the Cloud account.

In order to limit the amount of space your online files will take up on your device, you can set the maximum “cache size”. To do this, tap the “More” button and then choose Settings. Then tap on the individual cloud account and change the Max Cache Size to something else. The default cache size is set to 100 MB for each account. Keep in mind that all the files in your cloud account are not automatically downloaded to your device – only the ones that you choose to open. Instead you will see the list of files, with each of them “grayed out”. Once you tap on the file name, the file will be downloaded onto your device.
