Skip upload if file exists

[Fukitsu]

I want to upload a file but only if it doesn't exist. I'm trying with
dbx.files_upload(f.read(), BACKUPPATH, mode=WriteMode('add', None))
But if the file exists I get an ApiError like
UploadError('path', UploadWriteFailed(reason=WriteError('conflict', WriteConflictError('file', None))
How can I upload the file only if it doesn't exist and if it does just skip it (do nothing)?

Using the 'add' WriteMode like you already are in your example is the right way to do this. That tells Dropbox you want to add a new file, but not if something is already there. Accordingly, Dropbox rejects the upload with this 'conflict' error if a file already exists at that path.

In your app's code, you should catch this error (using except) so you can handle this error case however you wish. For instance, you can just ignore the exception if that's what you want your app to do.
