How to reduce dropbox internal data usage Currently both the DiskUsage app and Android's App Data show that Dropbox is using over 800 MB of internal sdcard storage space. Dropbox says it has no offline files. /storage/sdcard0/Android/data/com.dropbox.android shows no significant data usage.

Is there a way to clean this up without using the CLEAR DATA button in App Data? What will be the repercussions of using that button?
I have a rooted phone, and I found an > 800 MB file at :/data/data/com.dropbox.android/global/external/docpreviews. I just deleted it. This did result in additional free space, though I'm not sure if it will stay free or if there will be other repercussions.
