DBFILESWriteMode - please explain
Overwrite I know.
Please explain isUpdate and isAdd.
For example, what if I want to try and write a huge list of files to a dropbox folder. Is there a mode where I don't have to look at every file in the destination folder and compare modified dates before uploading?
What I mean is there a way to do a batch upload of all files and let dropbox decide whether the file needs to be written or updated using the writeMode?? This would be ideal if possible.
Thanks

Dropbox unfortunately doesn't distinguish between write and update. If any part of a file has changed, no matter how small, the entire file is re-uploaded.
What `isUpdate` allows you to do is manage the case where *nothing* has changed in the file, in which case, no upload is performed. You do this by getting the metadata for the file, storing it's revision, then passing the revision up to the server upon upload.
