This program requires VBRUN300.DLL. You may use this program free of charge and you need not register it; however, the interface for this program was written in Visual Basic. If you want to be able to modify this program for use in other programs or if you just don’t like the way it looks, the Visual Basic source code is available by registering (GO SWREG - $21.00, ID# 5391). The DLL (READARCH.DLL) does the actual decoding of the archives based on offsets into the binary file and has a couple of other utilities for reading the dates on some files and listing PIT archives. Everything else was done in VB so you can have the most flexibility to make changes to the interface. READARCH.DLL should be placed in your WINDOWS/SYSTEM directory or in the same directory as AV.EXE. Technical support for Archive Viewer is only available to registered users. This program is intended for private use and may not be included in commercial products or resold. Archive Viewer can extract files from the following archives with the listed compression methods: ARC/PAK None - Old style, no compression None - New style, no compression RLE - Compression of repeated characters only Huffman - Compression of repeated characters plus Huffman SQueezing 12 bit LZW - Lempel-Zev packing of repeated strings (old style) LZW w RLE - Lempel-Zev packing of repeated strings (new style) LZW w RLE - Lempel-Zev Williams packing with improved hash function LZW w RLE - Dynamic Lempel-Zev packing with adaptive reset Squashing - Dynamic Lempel-Zev packing, larger hash table ARJ No compression lz1 lz2 lz3 lz4 GZ GZIP LHARC lh0 lh1 lh4 lh5 lzs lz5 PIT No compression Huffman SIT No compression RLE compression LZW compression Huffman LZH TAR No compression ZIP No compression Shrunk Reduced(1) Reduced(2) Reduced(3) Reduced(4) Imploded 8K/D 2 Sfano Imploded 4K/D 2 SFano Imploded 8K/D 3 SFano Tokenized Deflated Z Unix Compress Unix Pack SCO LZH Compress ZOO No compression LZW LZH Archive Viewer can also decompress files compressed with Microsoft COMPRESS. Archive Viewer may take a long time to list the contents of PIT archives if the archive is compressed because it has to decompress the entire archive before the contents can be listed.
