Refresh Your Mobile Device Data
We recommend that you synchronize, or sync, your mobile device regularly to update the host system and your mobile device with any changes.
You might want to delete data periodically, which lets you manage your device memory and optimize performance by removing old files.
Don't delete data if you've made changes on your mobile client device and you haven't synced, because you'll lose those changes.
To delete data:
Select Setup.
Select Resco.
Scroll down to the ADVANCED section.
Next to the Delete Data field, select the Click Here link.
You'll be asked to confirm the deletion.
