If you like Dropsync please consider upgrading to Dropsync PRO.

PRO features include

* Sync multiple folders
* Sync the whole Dropbox with a folder on your phone or tablet
* Arbitrary upload file size limits, including "no limit"
* Instant upload: new files (for example photos) are uploaded to Dropbox immediately, no need to wait for the next autosync cycle
* No ads, of course

Dropsync PRO Key is available on Android Market. Installing the key will unlock PRO features in Dropsync. Contact the app developer if you can't buy paid apps on the Market, there is an alternative way to buy the key for the same price.
