For those who prefer Aladdin Stuffit on Windows, here some tips:
The following registry key will associate .jar files to that you can expand them with ease. A nice trick to have.
Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\.jar] "PerceivedType"="compressed" @="StuffIt.Zip.Archive.View" "CONTENT TYPE"="application/x-stuffit" [HKEY_CLASSES_ROOT\.jar\CompressedFolder [HKEY_CLASSES_ROOT\.jar\CompressedFolder\ShellNew] "Data"=hex:50,4b,05,06,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00 [HKEY_CLASSES_ROOT\.jar\OpenWithProgids] "CompressedFolder"="" [HKEY_CLASSES_ROOT\.jar\PersistentHandler] @="{098f2470-bae0-11cd-b579-08002b30bfeb}
Provided at your own risk.
Save the contents into a text file with the extension .reg. Then open it.
You can also go into the preferences and save without compression. Then just right click, and zip.
