The maximum size of a file is limited to the free space available on the disk volume where it resides.
12.
Logical Disk Manager enables disk volumes to be " dynamic ", in contrast to the standard " basic " volume format.
13.
Files may still span multiple disk volumes, and now the list of volume names is given when the file is created.
14.
Unlike other operating systems, the file naming hierarchy is independent of the location of a file on a particular tape or disk volume.
15.
On a system with more than one disk volume, it is thus easy to create functioning backups of a system simply by dragging the folder.
16.
Under Apple DOS, disks could only be given a volume number, but Apple Pascal disk volume names could be up to seven characters in length.
17.
Disk volumes are stored on traditional cylinder-track-record and fixed block architecture ( FBA ) disk drives or at one time on the IBM 2321 Data Cell.
18.
When you wish to encrypt individual files, copy them to an encrypted folder or encrypt the file " in place ", and then securely wipe the disk volume.
19.
DOS 3.3 did not support these drives natively; third-party software was required, and disks larger than about 400 kB had to be split up into multiple " virtual disk volumes ."
20.
:A common way to do backups in " highly available " systems is to have each disk volume replicated ( " shadowed " ) across ( say ) three physical disk drives.
