In order to permanently delete files from your Workspace, follow these simple steps:
Place files in Trash Bin
Select the file you wish to delete. In the blue action bar, click the 
More icon and select Trash. You can also right-click on the file and select Trash as shown in the figure below.
Figure 1: Right-click and select Trash
It's important to note that trashing certain files will result in them being removed from any associated MediaBoxes or WorkSessions and will close any active File Requests. In this case, a dialog will be displayed as a precaution before choosing to trash these files (see figure below). Further, only 500 files can be moved to the trash bin at a time.

Permanently delete files from Trash Bin
- Open the Trash Bin by selecting the
icon located on the left-hand side of the UI. - In order to permanently delete all the files in the Trash Bin, select Delete Forever near the top of the UI. This will completely purge all of the files in the Trash Bin.
- To permanently delete single or groups of files, select the files you wish to delete, right-click on a selected file and select Delete Forever from the drop-down menu.

Keeping files in the Trash Bin doesn't create more storage space. A user must purge their Trash Bin in order for more storage space to become available in the Workspace. To restore files that were trashed, right-click on the file and select Untrash (see figure 3). This will remove the file from the Trash Bin and return it to it's original folder location in the Workspace.
