JACZip (Beta) Back to Home Page

JACZip is a straight forward ZIP Archive/Unarchive program using the built in facilities within Windows. The Microsoft implementation of the ZIP function into the Windows Explorer is to say the least cumbersome, and with WinZip you never really know what it has done. If the old Command Line PKZIP supported long file names, I would probably still be using it.

JACZip is written in VB6, and is being made available in ZIP format. Installation is usually straight forward, using "setup.exe" to install files extracted from "JACZip.cab" as laid out in "setup.lst".

The menu in JACZip is very limited. It basically consists of View a Zip File, UnZip a File, and ZIP selected files. Rather than explain how to use these functions (which is pretty straight forward), it would probably be more useful to describe how it works.

To view a Zip file, you simply use the Windows Open Dialog to find and select the file, and the results are displayed in a grid box. By default it expects the extension to be ".zip", although it should support any archive file that Microsoft supports (such as ".cab").

To UnZip a Zipped file, you would again use the Windows Open Dialog to find the file, and then a standard "Browse for Folder" window allows you to select the destination. Unlike other UnZip programs JACZip does not use the PATH information. It simply deposits the files in the location you have selected.

JACZip uses a temporary directory in the Users %Temp% directory (folder) to collect files that you select using the "Get Files" menu item. This window supports multiple file selection, but there is a limit to the number of files that can be collected in one pass (somewhere between 30 & 50 depending on name length). The selected files are displayed in the grid box, and once you have all the files needed, you click the "Zip Now" menu item. You are asked to enter the file name (".zip" extension will be added if no extension is provided), and select the destination directory (folder). The program will wait to verify that the ZIP file has actually been created/updated. This is necessary because upon successful completion, the temporary directory is deleted. If you are updating an existing ZIP file, the operating system will prompt you to overwrite each file being updated. This is a standard Windows function that cannot be overridden. If for some reason there are files left behind in the temporary directory, there is an additional menu item to clear the temporary directory.
