How often do my offline folders update?

Dropbox checks if any changes were made to your offline folders when you open the Offline tab. If changes were made, Dropbox syncs these changes to your device when your device is connected to WiFi. When your device is not connected to WiFi, changes are indicated by a yellow "!", and you can tap to update them manually. If you'd like folders to update using data (when you're not connected to WiFi), go to your settings and toggle Use Cellular Data to on.

Do offline folders update while the app is in the background?

Automatic syncing while the app is in the background is not currently supported. The only exception is when Android devices are connected to power, offline files sync in the background.

Is there a limit on the number or size of folders I can make available offline?

You can make up to 100 folders available offline.

A folder can't be saved for offline use if:

The folder contains more than 10,000 files
The folder contains more than 100 GB
The folder contains a file that is more than 10 GB

Why am I seeing a red "x" next to the folder that I made available offline?

There can be a few different explanations for a red "x" on the folder icon, including:

Your device has less than 500 MB available
The folder contains more than 10,000 files
The folder contains more than 100 GB
The folder contains a file that is more than 10 GB

Why am I seeing a yellow “!” next to the folder that I made available offline?

A yellow exclamation point means that a newer version of your folder is available. Tapping the refresh icon on iOS or Update all button on Android syncs these changes.

Do offline folders use my cellular data?

When the Dropbox app is open, any changes automatically sync to your phone. If these changes are greater than 20 MB, you can decide whether you’d like to wait for WiFi or sync the changes anyway. If you'd like folders to update using data (when you're not connected to WiFi), go to your settings and toggle Use Cellular Data to on.

Do offline folders use up my device storage space?

Yes. Folders that are marked to be available offline are stored locally on your device. If you have less than 500 MB of storage available, syncing automatically stops.
