PC Dual Revision Narrative historyPC: Dual-1.exe (10-29-2004): This one assumes ZIP drive is D: or E: (PC).PC: Dual-2.exe (11-12-2004): This one is: 'DIFF.EXE' stops reading a pair of catalogs at the same time; Root 'Dir.Txt' misses two top directories; No 'GrandSum.Txt' (Grand Summary). PC: Dual-3.exe (01-26-2005): From Oct-2004 to Jan-2005, assuming Win95/98 only. Longer folder names are cut down at DIFF reports. PC: Dual-4.exe (02-13-2005): Assuming scanning folders are 1-99, more than 100 folders, the DIFF reports are cut off at 99. 'GrandSum.Txt' reports well. PC: Dual-5.exe (06-04-2005): All PC versions up to this assumes Shadow Hard Disk (SDW) as "C: " (drive name). PC: Dual-6.exe (07-22-2005): All PC versions up to this use command "DIR", while the newer version use "DIR /B" (brief switch). Detail internal messages are present in this 07-22-2005 version, but most of them are taken out from the latest version. PC: Dual-7.exe (12-24-2006): All PC versions up to this version works with so-so length of folder names such as up to 50 characters. To work with very longer folder names, internal codes are adjusted from [64] to [128] at current Dual.exe (posted date 08-27-2008).
