General Information
Assigning Names to Directories and Drives:
It is possible to assign a name to a directory in the drive and dir list.
This can be achieved by defining in Standard Adjustments/Paths, for example:
c:\windows>Win95
Most commands that need some pathnames or filenames as arguments
accept this assigned name (here: Win95) as drivename.
Therefor you can enter, in the path gadget for example:
Win95
and you will be put to c:\windows.
You can access the file win.ini in the c:\windows directory by entering:
win95:\win.ini
This cuts some things short !
The Standard Requester
PCOpus uses an internal standard requester for error reports, rename, makedir, etc.
Well, nearly everything is done with this requester.
When you have to enter something into the (lower) text-gadget, you can use
- F1 and F2 accompanied by Shift to select the files from the directory window.
- F1 without Shift adds the first/next selected entry from the ACTIVE side to the gadget
- F1 with Shift adds the first/next entry (if selected or not) from the ACTIVE side to the gadget
- F2 without Shift adds then first/next selected entry from the INACTIVE side to the gadget
- F2 with Shift adds the first/next entry (if selected ot not) from the INACTIVE side to the gadget
You may search through all entries by pressing the keys more than one time.
You may find this useful perhaps.
Supported Filetypes:
- ARJ Archives
Archives created by the archiver ARJ.
Files MUST end in 'ARJ' and must be ARJ-Archives.
From version 2.60 ARJ supports long filenames.

- JAR Archives
Archives created by the archiver JAR.
This is the new archiver from ARJ-Software, with really good compression ratios.
Unfortunately the structure of JAR archives is a real mystery to me. As long as R.Jung
does not supply the structure of JAR archives, PCOpus uses the JAR lt command to create
a file-list in the temporary directory and reads the archive contents from this file.
This is really slow, but it works, what is the main thing.

- ZIP Archives
Well known on PC platforms should be ZIP files.
Files MUST end in 'ZIP' and must be ZIP-Archives.
Please take care that PKZIP and PKUNZIP can only handle 8+3 DOS
names. If you want to extract files from the archives all names are
shortened to 8+3 by PKUNZIP. Use WinZIP if you need full support for
long filenames.
The Unzip32.dll from Info-Zip is used now and is delivered with PCOpus now.
If the use of the DLL is not explicitely forbidden in Standard adjustments/Archive,
ZIP extraction is really fast and supports long filenames, too.
- RAR Archives
The 'Russian Archiver' is on the best way to become the standard archiver. It is unsurpassed in
compression ratio (and compression time :-))
Files MUST end in 'RAR' and must be RAR-Archives.
PCOpus can use the unrar.dll from E.Roshal now.
- LHA/LZH Archives
A very old Archiver, mostly used on Amiga, I think, is LHA and its predecessors.
Files must end in 'LHA' or 'LZH' and must be LHA-Archives.
- D64 Disk Images
The Commodore 64 diskimage files, introduced by Miha Peternel, creator of C64S.
Files MUST end in 'D64', everything
is treated as D64 file then. Please note, that the output will be
quite strange if the file is not a real D64 diskimage.
A special 'D64-Rename' has been implemented that allows renaming
of the files inside the diskimage. Please use only backup-copies of
your diskimages. Not that the routine is buggy, but if you changed
names and forgot the original name it is easily possible, that
the C64 programs won't run. Click on the standard Rename button
to rename files.
- CAB Archives
Micros*ft cabinet files. You know them.
Files must end in 'CAB' and must begin with 'MSCF' inside the file.
CAB files have some restrictions compared to normal archives.
The 'extract.exe' must be in your path. 'Extract.exe' does not
support extracting of complete directories, at least as far as I
know. Therefore you can only extract single files (of course
more than one at once), but no directories. If you need to extract
all files from a CAB file, including all subdirs, define a button
with an external command like:
path\extract.exe /Y /L {d} /E {f}
Please check the command line options of extract before defining
a button.
We have come across some CAB-files that are NOT compatible to standard CAB-Files.
We will implement support for them on request.
- ISO Images
ISO9660 CD-Image files
Files must end in 'ISO'.
Mode 1 and Mode 2 (XA) is supported.
Since Mode 2 is quite strange (304 unused bytes ?) and the structure
is a bit different to Mode 1, files from Mode 2 images are copied with
a chunksize of 2048. This results in fairly longer times to copy files.
PCOpus is the first program to do this under Win95 as far as I know.
- FCD Images
Fast CD Personal Edition v1.0 uncompressed image files.
Files must end in 'FCD'.
See ISO Images for details
- CP Backup .DIR files
The catalog-files of PCTools backups. contents can be viewed
The whole archive support was programmed without a single line of
documentation. So it is easily possible that you stumble over an
archive file that is not correctly read. Please send an EMail with
an exact description of the problem to msiegris@student.uni-kl.de
If there is an urgent need for support of any other archive-type, I will
try to implement them on request.
NOTE 1: PCOpus uses Info-Zips unzip32.dll. Info-ZIP's software (Zip,
UnZip and related utilities) is free and can be obtained
as source code or executables from Internet/WWW sites,
including http://www.cdrom.com/pub/infozip/
NOTE 2: PCOpus uses E.Roshals unrar.dll that comes with WinRAR.
