BBS DESCRIPTION
~~~~~~~~~~~~~~~
EXTRACT 2.10: Extract files from disk image using PKUNZIP UNARJ like
syntax. Extract files from floppy image created by WinImage (same
author), DCF, DF, Sabdu, and many other disk copy tools which create
a disk image. Versions for DOS and for NT. You can create image and
inject a file onto it. NOW FREEWARE!
EXTRACTING A FILE FROM A DISK IMAGE
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Extract is a command line disk image file extraction utility.
An image is a file which contains all the floppy data (boot sector,
FATs, directories, files...) of the original floppy.
Sometimes found with a .DSK or .IMA extension, the image can be restored
to another floppy in the original state as an exact duplicate
of the original.
An image file can be created using WinImage (for Windows 3.1,
Windows'95 and NT) a shareware program I wrote which creates
and manages image files using a superset of Extract functionally,
or many other DOS based disk copy utilities such as:
- Wimage (in FdFormat utility) from C.H. Hochststter
- DrDos 6 and OS/2 2.x and 3.x diskimage utility
- DCF (Disk Copy Fast) from Chang Ping Lee
- CopyVit from Sebastien Chatard
- DF (Disk Image File Utility) from Mark Vitt
- Super-DiskCopy from Super Software
- SabDu from S.A. Berman
- Disk-RW from K. Hartnegg
- DiskDupe from Micro System Design
- The internal disk image utility from Microsoft and Lotus
- MFMT sample Windows NT application on the Windows NT SDK.
After tests we found 80% of the diskcopy tools which can make images
are compatible with Extract and WinImage.
EXTRACT - USAGE
~~~~~~~~~~~~~~~
If you run Extract without parameters, you will see the following
usage information.
Extract -l <file> [<Files names>] List file in an image
Extract -e <file> [x:outpath] [<Files names>] Extract files
Extract -x <file> [x:outpath] [<Files names>] eXtract files with pathname
Extract -i <file> [<Files names>] [-Fnnn] Inject files on an image
Using -oe or -ox instead -e or -x extract Overwriting existing files
Using -it instead -i Truncate unused image part
-Fnnn : size of image you want create (360,720,120,144,172,288...)
Extract's syntax is patterned after the PKZIP/PKUNZIP and ARJ syntax
model.
The first parameter must be -i, -it, -l, -e, -o, -x, -oe or
-ox. If the first parameter is the image filename, the -l (list
option) is understood by default. The second parameter is the image
filename, you may use wildcards (*/?) and Extract will use all the
files it finds matching. The third parameter is the optional path
where you want Extract to place your extracted files. You must begin
this parameter the drive and directory (x:\xxxx). If you use only the
irectory name, extract will not consider it as a proper path.
If the first parameter is not -i or -it, you can specify wildcards to
select files in images. If you do not specify a file name, Extract
selects all files in the image. If the first parameter is -i or -it,
it specifies a filename you want injected into the image (or -Fxxx to
specify the format of the image you want to build).
[ Example ]
We are in the C:\REP1 subdirectory, and we created C:\REP2
subdirectory. In C:\REP1 we have DISK1.IMA and DISK2.IMA disk images
created with WinImage.
DISK1.IMA is the image of a floppy containing these files:
DOC1.TXT
DOC1.DOC
DOC1A.TXT
DISK2.IMA is the image of a floppy containing these files:
DOC2.TXT
DOC2.DOC
DOC2A.TXT
DOC2R\DOC2B.TXT (a subdirectory DOC2R containing DOC2B.TXT)
If we execute Extract with these parameters...
EXTRACT -L DISK?.IMA
Extract will list the directories and contents of DISK1.IMA and
DISK2.IMA
If we execute Extract with these parameters...
EXTRACT -E DISK?.IMA
Extract will extract the contents of DISK1.IMA and DISK2.IMA
C:\REP1\DOC1.TXT
C:\REP1\DOC1.DOC
C:\REP1\DOC1A.TXT
C:\REP1\DOC2.TXT
C:\REP1\DOC2.DOC
C:\REP1\DOC2A.TXT
C:\REP1\DOC2B.TXT
If we execute Extract with these parameters...
EXTRACT -X DISK?.IMA
Extract will create the directory C:\REP1\DOC2R and the files
C:\REP1\DOC1.TXT
C:\REP1\DOC1.DOC
C:\REP1\DOC1A.TXT
C:\REP1\DOC2.TXT
C:\REP1\DOC2.DOC
C:\REP1\DOC2A.TXT
C:\REP1\DOC2R\DOC2B.TXT
EXTRACT -X DISK?.IMA C:\REP2 *.DOC DOC2B.TXT
Extract will create the directory C:\REP2\DOC2R and the files
C:\REP2\DOC1.DOC
C:\REP2\DOC2.DOC
C:\REP2\DOC2R\DOC2B.TXT
EXTRACT -I NEWDISK.IMA C:\CONFIG.SYS C:\COMMAND.COM -F144
Extract will build a new image with the 1.44 Mb format size, and put
the files CONFIG.SYS and COMMAND.COM into NEWDISK.IMA
EXTRACT -I DISK.IMA C:\AUTOEXEC.BAT
Extract will add the file AUTOEXEC.BAT into DISK.IMA.
When using -E or -X Extract will delete an existing file and ask for
confirmation before deletion.
When using -OE or -OX it will not ask for confirmation.
