I'd like to make new topic, concerning the idea, given in another topic about idevsutil-api (http://forum.idrive.com/topic.php?id=128).
But my proposal is about such feature in the web client. I'll explain my idea in details.
First I'll remind (just for the sake of pointing the difference with my idea) how works in the moment the upload-action in the web client - it adds and updates all sub-items in the corresponding folder on the server (if it exists, otherwise it creates it and adds all the sub-items).
My idea is to have new button (let's name it "Upload with cleanup"). And the action to be as the current upload-button with the difference that it will DELETE the sub-items that don't exist in the source (local) folder.
I believe other people would like this feature too.
I've told in the other topic that I really like the web client, and the lack of this feature is the only functional lack I see.
