What is ADU/2 ?

ADU/2 is a file and directory management tool intended for administrators
of large disks running in an OS/2 environment. Two years ago it's main
focus were great enterprise LAN's consisting of many IBM LAN-Servers
or Microsofts LAN-Managers. (OS/2 Netware clients are appreciated as well
especially if OS/2 naming support runs at the server). A GUI based tool
may be nice, but if time is money .....

In 1993 a lot of people run the superior OS/2 HPFS instead of the FAT file
system and they would like to exploit the new features. And that's exactly
what ADU/2 supports. It handles easily all of the trivial file and directory
operations with LONG FILENAMES by preserving the EXTENDED ATTRIBUTES.

ADU/2 is a fast filemanager with a text-based interface. ADU/2 runs either
in a PM-Window or fullscreen session.

Main highlights

- HPFS Support (EA's and Long Filenames)

- No installation required

- Small, so it is startable from diskette

- Does not modify systems ini files nor create any unwanted files

- Usable on diskette booted systems ( PM or WPS not required )

- Save directory trees to user named files. That's very convenient
for large and slow medias like CD-ROM or MO-Disks

- Scanning, refreshing and display of subtrees is possible. Think of
great server disks with thousends of directories requiring several
minutes for scanning the whole directory tree.

- detailed overview about the disk space consumption listed by
directories and subtrees.

- Very fast seek and scan files function with many options:
filespec, attributes, last write , last access, creation,
size, EA-Size, string pattern, base path.

- An easy to use Hexeditor

- Fine for IBM LAN-Server or Microsofts LAN-Manager network environments
UNC-Names are supported for most of all operations.

ADU/2 Philosophy

The ADU/2 user interface reflects the main intention of the ADU/2
development: There should be no time consumption by opening, moving,
sizing windows and menues. Each action should be invoked by one or
two keys. The provided menu is not necessary for using ADU/2. The
menu is for beginners and could be used as a help for learning the
short cuts. The help function invoked by F1 represents only a condensed
overview about ADU/2's keys and functions.

ADU/2 needs only one file for operating and that's ADU.EXE. So no
installion is required and for service and maintenance in an organisation
it's startable from diskette. ADU/2 does not modify any system files or
create files by itself because that is unacceptable in LAN environments.
Mouse support is included even there is mostly no gain in time, but you
may find it convenient if ADU/2 runs in a windowed session.


Invoking ADU/2

ADU/2 is simply invoked from an OS/2 command prompt either in a windowed
or fullscreen session by typing ADU.

Terminating ADU/2 is made easy. Experienced user will press ALT-X at any
time they want to quit and there will be no boring prompt. Another way is
to press ESCAPE until your are prompted for terminating ADU/2.

The ADUEDIT Environment Variable

Pressing the letter E in the File/Directory screen invokes the OS/2 systems
editor e.exe with the highlighted entry as a parameter.
If you would like to call your favorite editor you could specify it in the
option menu. By terminating ADU/2 this information is lost. Setting the
environment variable ADUEDIT will overcome this problem. For permanent use
in all sessions you have to do it in the config.sys. For example if your
favorite editor ist q.exe and you would like run q.exe in fullscreen mode
add the following line to your config.sys:


Other switches are /PM and /WIN. If no switch is given the program will
determine the session mode.

3. HOW CAN I ...

copy, move, rename, view, delete ...

We think this is fairly self-explanatory.

Display two file lists simultaneous

For convenient file/directory move and copy operations you can open a
second list by pressing CTRL RETURN. The inactive list is always the
default target path. The TAB key changes the active list.

Open a quick action context menu

clicking the right mouse button in list area opens a special
quick action menu refering to the highlighted or marked item(s).

Show long filenames

File/directory names exceeding the 8.3 FAT naming conventions may
not be displayed with their full names. This is indicated by three
succeeding dots. You can zoom the highlighted entry to the full name
by pressing 'Z'. In the file/directory list it is also possible to
scroll the names by pressing the right or left direction key.

Display 'last access' and 'creation' date

Pressing F2 switches the displayed file date mode. Default mode is the
FAT supported last 'write access'. Pressing F2 once switches to
'last access' mode and another F2 shows the file 'creation' date.

Get a file list with EA size

Ctrl-X toggles display mode: Extended Attributes size and time data.

Get a detailed EA view

Pressing X in the file list displays the EA Data for the highlighted entry

Print files,lists and trees

Dependent on the work area pressing 'P' invokes the creation of tree or
list print file. You will be prompted for the name of the print file.
Specifying LPT1, for example will cause a direct print.

You can print one or more ASCII-File(s) by invoking the copy function
with 'C' or Ctrl-C and specify the target path as e.g. LPT1, LPT2 ...
or an UNC-Name like \\server1\hplaser.

Display the entry screen

Pressing F12 in the file list area displays the entry screen from which
ADU/2 was started.

Group files and directories by using masks

Advanced marking and unmarking files/directories for further processing
could be done with '+' and/or '-'.

Use list entries as execution arguments

Alt-Return prompts you for an executable file e.g. VIEW, UNZIP ...
which uses the highlighted entry as an argument. Additional arguments
could be supplied.

Control the confirm status

The default status of the confirm toggle is ON. So you are prompted
for confirmation in the case of:

- deleting
- overwriting
- case changing

ALT-C toggles the confirm status ( only in the file list screen )

While processing a group of files/directories you can overide the
confirm status temporary. Choose 'Rest without confirm' when the
first confirmation prompt comes up.

Change the case of file/directory names on HPFS drives

Simply press F7 to swap the highlighted entry to upper case, Shift F7
for lower case. Ctrl F7 refers to the marked list entries.

- 6 -

Read and refresh subtrees

For extended directory structures it could save much time to scan
only a subtree. Change to the desired basepath in file list screen
and press then F9. Refreshing subtree data beneath a highlighted
tree entry is done by pressing Ctrl-F5 in the tree display.

Save and restore directory tree data to user named files

For slow and large media like CD-ROM's and MO's it is very
convenient to save a scanned tree. This is done by pressing
ALT-W in the tree screen. ALT-R restores a previous saved
tree. This could be done either in the file/directory list
screen or the tree screen.

Display space consumption listed by directory and subtrees

Press F2 in the tree screen to change the size mode. The allocated
space is shown beside each directory name. The following modes are
available pressing F2 multiple times:

- no size shown (default)
- space allocated in directories
- sum of space allocated in subtrees
- extended attributes size related to the directory itself

- a little dot preceding the directory name indicates the existence
of extended attributes for this name. This is similar to the little
'x' in the file list screen.

Get a more handy tree display

You can restrict the tree display to one or two levels by pressing
'1' or '2'. Pressing '0' will expand all branches. Collapsing or
expanding of a single branch could be done by pressing '-' or '+' for
the highlighted tree entry. Clicking the left mouse button on the
horizontal tree lines will hide the subtree. The tree line will then end
with an arrow representing a hidden subtree. Clicking on these arrows
will unhide the subtree.

Recall recent used move and copy target paths

Whenever you are prompted for a target path of a copy or move operation,
a list of recently used target paths could be provided. Simply press F4.

Establish LAN-Connections

Pressing 'J' assigns a drive to a LAN resource. Example : You got a
IBM LAN-Server or a Microsoft LAN-Manager named APPSERV and shared
resource named APPSDATA. After pressing 'J' the drive to assign is by
default the next free unassigned drive. Type \\APPSERV\APPSDATA in the
input field for the 'shared name'. 'K' release a LAN-Connection to drive.

Edit input fields

CTRL Y deletes the rest of input field.
CTRL T delete the next word

INSERT toggles insert mode
DEL deletes the single character under the cursor
BACKSPACE deletes the single character left of the cursor

Cursor placement
CTRL -> forward to the beginning of the next word
CTRL <- backward to the end of the previous word
HOME at the beginning of the input field
END after the last nonblank character
CTRL HOME in the first input field
CTRL END in the last input field
TAB or in the next input field
SHIFT TAB or in the previous input field

Some input fields are cleared automatically if the first pressed
key is no direction key.
