Duplicate, unskippable dialogue boxes when uploading a duplicate folder.

[stevefunk]

Behavior

If a user begins uploading a folder into Sia-UI, and then attempts to upload the same folder again, a dialogue:

upload failed: a file already exists in that location

is presented for every single file.

Problem

A user must acknowledge every dialogue box, which could be especially troublesome if there are hundreds or thousands of files in the folder.

Solution

The standard "acknowledge this for every file" or some other method of not having to click/press Return once for each file.
