Certain disks, like your GEOS system disk or application disks, are sometimes given a designation of BOOT or MASTER, which helps protect the data on these disks from being accidentally deleted or overwritten. So, if you happen to create a new data file and store it one of these disks (which you really shouldn't do), you may find that the system prevents you from moving these files to the trash for deletion.

There is still a relatively simple way for you delete these data files. What you need to do is, rather than move the file (with the desktop pointer) directly to the trash can, first move it to the bottom border. Once you move it to the bottom border of the desktop's workspace, you can then click on it and move it to the trash can.
