on the drive, directory name, or filename.

b.Type: column displays the extension of the filename, for example,

.STA or .TRC. Directories are displayed as DIR and drives have

nothing listed under Type:. They are only designated by the

Name: column ([-A-] or [-C-]).

c.Size: column displays the size of the file in bytes.

d.Modified: column displays the date and time the last change occurred.

3.The softkey menu has four options:

a.Type: allows you to choose the type of file you wish to view. (You may view all types by using the All key under Type.)

b.Sort: Under the Sort key, you can sort by any of the four columns and you can choose up (ascending) or down (descending).

c.Dir Up: moves you up one directory level. If you are already at the top level, this key moves you up to the drive level, displaying the available disk drives.

d.Dir Select: moves you down into the highlighted directory or up into the next level (directory or drive) if the “. .” under the Name: column is highlighted.

NOTE

Navigation keys: Use the front-panel Step Keys or Knob and the Dir Up

 

or Dir Select keys to move around in the directory information box.

 

4. The drive space line shows the number of bytes used on the drive

 

and the number of bytes still free on the drive.

Creating a directory

Directories and sub-directories can be created on both the A: floppy disk

and the internal C: drive. This allows maximum flexibility in organizing files. For this example, we will create a directory on the C: drive.

1. Press File, More 1 of 2, Create Dir. Your screen should look similar to Figure 4-1, except the entry fields will be Dir Name: and Path: and the Heading will read: Directories.

2. Navigate through the file system until the Path: field displays C:\. (Use the Step Keys, Knob, Dir Up, and/or Dir Select keys.)

3. Press Name and enter the name, “START” using the Alpha Editor. (The numeric keypad is also available for the filename.) Press Enter (hardkey) when the Dir Name: field contains this directory title. (Use the Bk Sp hardkey on the front panel to make corrections.)

4. Press Create Dir Now to execute the operation. The message:
