I CANT FIND THE SPACE WHERE YOU CAN DRAG AND DROP FILES INTO WORKSPACES. HELP?

Once you have Workspaces open, and have clicked onto a project or have created a project click onto the file(s) and drag them to the lower left hand corner of the dark sidebar. A box will appear that says "Drop files to download". Drop the files (release your mouse button) into the box. You will see the box, once you drag the files over the left lower sidebar. Once they upload they will appear toward the top of the left-hand sidebar. From there you will be able to create folders and drag the files into the folders to organize them as needed.

i cant pull up the box that says drop files to download when i hover the the files over the sidebar. all i get is a red circle with a red line through it. I don't know what I am doing wrong.

I know that some people have reported having to close workspaces and restart it and others have switched to a different browser such as Chrome, and that fixed their problem. If you are trying to upload a folder of image files, you might want to try to open up the folder and just drag and drop the image files themselves into the box. You can always create a new img folder in workspaces and add them to the folder. I would try uploading your files with the Chrome browser first.
