You might imagine these to be in a batch condition, where one writes eg "pack winfile.ex e". destArg can be a directory,Ī specific filebase, or omitted in which case digits are appended. SrcArg can be a filename, a wildcard pattern, or a directory. z will split off and compress just one piece, and leave the Text that includes spaces should be double-quoted. t will include following Text in the header. With a sequentially higher numerical base name. s will split output into Size x 512 byte pieces naming each piece q will compute compressed file lengths (no output) (ignores -sz flags). l will include each file length in the header. f will force overwriting and recompression of files. be will include each file basename/extension in the header. a - Choices for compression algorithm are: ģ - Jeff Johnson's algorithm (LZSS + Huffman). Usage: compress srcArg Microsoft (R) Compression Utility - Version 1.02Ĭopyright (c) Microsoft Corp 1989 - 1991. Still, because of fears of it being overwritten, i renamed it to ENCOMP (to match DECOMP). I found it in conjuction with the Foxpro distribution Kit.

On the other hand, the expand from dos 5.0 or Windows 3.x0 (3.00/3.10/3.30) is incapable of expanding KWAJ format. One notes also that there is an OS/2 utility DECOMP.EXE, (included in the WLO libraries), which is quite capable of expanding the Windows 3.11 / DOS 6 files. EXPAND 2 (in DOS 6.x), and 2.1 (in Windows 3.11), are there largely to handle both SZDD and KWAJ formats transparently. But because Windows 3.11 and DOS 6 are considerably larger than their DOS 5 / Windows 3.10, the older format was reused to save disk storage. One might easily suppose that SZDD is native microsoft format, but did not give the same compression ratios as an earlier KWAJ. MSCF is generally as good as KWAJ, but appeared later. To understand what has happened, KWAJ is an older format than SZDD, but is generally better compression. One has to go way back to find a compress.exe for the KWAJ format. The "compress.exe" that comes with the Windows NT resource kit makes MSCF files. This is fairly easy to come by, it basically escaped the Windows 3.1 SDK. One can make SZDD files using a MS utility hight "compress.exe". The Dos 6 / Win 3.x1 files have here KWAJ. Looking in an DOS 5.x or Win3.x0 distro file, one sees the signature letters SZDD. The first element is to deal with the fact that both PC-DOS / MS-DOS and Windows 3.11 are compressed in the distribution. None the same, these are more cosmetic changes, rather than real things.

You should be able to access MS-DOS 6.22 and Windows 3.10 as well, because we will borrow from both of these. Initial tests with W310, W311 and W331 suggest that W331 requires the least modifications, and this version is fairly accessable to many users. One subject to be added is help on the Progman DDE interface. Eventually, we will get around to recompiling help files, to add in extra information. The further idea is to see if we can support something like standard mode in Windows 3.11.įor as much as possible, the process is not merely to produce a 3.31 distro, but to see if much of the original can be reproduced, including compression, etc. wfw 310 (w330) is also cheerfully dubbed "Windows for Warehouses", because it was slower than Windows 3.10 or either of the 3.11 stock. There really was a wfw 310 and an win 311, but neither of these were mainstream.

The base versions of Windows are abbreviated thus: So this is not merely some theoretical exercise, but a day-to-day OS. A custom build of windows has been used as the main OS since about 1994 to 1998 (when win31 dominated the desktop). This is not the first time this experiment has been conducted. Still, doing this gives a ready-made custom Windows with patches installed. The Windows 3.11 resource kit (reskit31.exe) gives extensive details on this, so we're really following what MS has documented.

In essence, while we are trying to keep with the original windows, most of the thing is getting a modern makeover.
