- /h Display help information.
- d:path\ DOS drive and/or path identifier.
- ARCfile ARChive file name, wildcards *,? ok.
- If no extension is given .ARC is assumed.

- drive & subdirectory storing extracted files on drive C:.
-
- PKXARC c:\lotus\tax -*.wks

- PKXARC warnings
- ---------------
-
- Warning! File YYY already exists! overwrite (y/n)?
-
- - A file to be extracted from the ARChive already exists on disk. Answer
- "y" to extract the file from the archive anyway and overwrite the
- existing file, "n" to not extract the file from the archive. Use the
- "/r" command line option to suppress this warning.
-
- Unknown packing method for file YYY
- - The file is squeezed or encoded in a unkown way. The ARChive is
- probably corrupt.
-
- Warning! File YYY fails CRC check
- - The Cyclic Redundancy Check calculation did not match the stored value.
- The file is probably corrupt.
-
- XXX is not an archive
- - The ARChive file header does not indicate this is an ARChive file.
-
- Archive length error
- - A end of file token was not found for a file within the ARChive. The
- ARChive is corrupt.
-
-
- PKXARC errors
- -------------
-
- PKXARC: can't find XXX
- - The given ARChive filename could not be found.
-
- PKXARC: cannot read archive: XXX
- - The ARChive could not be opened.
-
- PKXARC: Cannot create: YYY
- - The output file could not be created. The output directory is invalid
- or full.
-
- PKXARC: File has invalid decode tree
- - The Huffman decode tree for the file is invalid. The ARChive is
- corrupt.
-
- PKXARC: Disk full
- - A write to the output file failed. The disk is most likely full.

-
- PKXARC history
- --------------
-
- Soon after the ARChive file format was introduced into the public domain it
- became popular, and many BBS files were transfered this way. The ARChive
- format is a convenient way to put several files into one and squeeze them
- for effecient disk storage and reduced transfer time, in one step.
-
- However, the ARChive utility was much slower at extracting files than
- equivalent UnSQueeze type programs. In the inevitable quest for faster
- ARChive file extraction, PKXARC was created.
-
-
- Changes in PKXARC version 2.3
- -----------------------------
-
- The ability to extract dynamic Lempel-Zev encoded files was added. Version
- 5.0 of ARC introduced a new, more efficient variation of Lempel-Zev
- "Crunching". PKXARC can now extract files Crunched with this method,
- approximately 3 times faster than ARC 5.1.
-
-
- Changes in PKXARC version 2.4
- -----------------------------
-
- Performance for extracting dynamic Lempel-Zev files has been improved.
- Files which are identified as "Crunched" (with a capitol C) on the ARC
- verbose listing extract 15-20% faster than before.
-
- When a "Disk full" error occurred, previous versions of PKXARC would leave
- an empty or incomplete file on the disk. PKXARC now deletes any incomplete
- files before aborting with a "Disk full" error.
-
-
- Changes in PKXARC version 2.5
- -----------------------------
-
- The ability to extract specific files was added. PKXARC can now be passed
- the specific names of files to be extracted from an ARChive on the command
- line.
-
-
- Changes in PKXARC version 2.6
- -----------------------------
-
- Extraction performance for all compression types has been significantly
- improved over PKXARC version 2.5. Files that are crunched with older
- versions of ARC (pre 5.x) extract 5% faster. SQueezed files extract 15%
- faster. Files that are Crunched with ARC 5.x extract 20% faster.
