Most of the time you won’t want to use this screen to upload! Instead, use the drag & drop area from the File Manager main screen.

This screen lets you upload multiple files by changing the name and setting properties during the upload. It also lets you get files directly from an URL pointing to somewhere else on the World Wide Web.

Select each file to upload by clicking on the "Browse…" buttons. If you need to upload more than 5 files, click on "Add another file".

Once you have selected all the files you want to upload, click on "Upload to server now".

If you try to upload too many large files at once, you will hit various max size limits and the upload will fail. In this case, try to raise the limits or to upload less files simultaneously.
