You can get the disk properties dialog using the Edit|Properties menu item, or from the Properties item in the popup menu:
The detailed information about your disk is there: disk serial number; disk root path; drive type (floppy, hard disk, CD-ROM or removable); the date and time when you’ve added (or updated) this disk; total and available disk space; and the number of files and folders on this disk.
You can assign the name to the disk – it’ll be visible in left ADC window. By default, it is just the volume label (if there is one), or “Disk X” string (where ‘X’ is the drive letter).
To assign the category to your disks, select the appropriate one from the combo box (you can use the button on the right to edit categories list).
Feel free to add any comments to the disk by entering them in the window at the bottom. Typically, the comments briefly describe the disk contents (as on the picture above).
After you’ll close this dialog, if you’ve changed the disk category, you’ll be prompted would you like to assign the new category to all folders on files on this disk.
