Low on storage, you say? If you’re a heavy Dropbox user who’s running out of storage space on their device, clearing the app’s cache should be first order of business. The mobile app keeps a cache of files for efficiency and emergency purposes, aside from doubling as a staging area for downloading and uploading.
Flushing the cache should help free up some storage space on your iOS device.
Doing so is likely to cause files to load longer, but none of the offline items will be affected. If you’d like to free up some storage space on your iPhone, iPad or iPod touch, follow the steps outlined in this tutorial to clear the Dropbox cache with just a few taps.
