Files uploaded in comments, discussions, and updates will show up here. You can sort them by date uploaded so you can easily find files you're looking for.
If you want to download multiple files at the same time, hold "Shift" and select on the files you want to download, and simply right click and download. It also works for one file.
Perhaps you just want to take a peak at a document for a certain information you need, it may take longer to download the file just for that. In Bloo, you can "Right Click" on the file and select "Preview" to take a quick look.
You can also trace back to where the file is originally uploaded by Right Click + Locate.
