I want to maintain a large file synced between my android device and a PC. I will be doing small changes to this file file all the time on the device, and I want these changes to be reflected on the PC. Ideally the file should not be uploaded in full everytime it changes (because it is so big), but only the
differential changes (which are small). Is there a tool / app that does this? Does Dropbox / Dropsync work like this?
Update: This says that Dropbox only uploads the differential part. But I do not know if the same applies to Dropsync.
