I want to write a small application to backup data files for an application I have written. I need to be able to write code that will zip all the data files into a single zip which can later be unzipped (extracted) to restore the data files when necessary. I have read something about Inf-Zip, I haven't quite got around to understanding how to use the win32 DLL's.

Molefe,

I would suggest you invoke/spawn some already existing tool such as PKZip/WZZip if you are running under Windows. If you really need to go for Code and have access to 'C' then a tool called CCUnzip is available as both app and 'C' source from www.programmersheaven.com. I found this particularly useful recently.

Please clarify:

1) What platform.
2) What Language.
3) Do you want the zipped files in standard form (e.g. WinZip/PKZip) or can they be proprietary?
4) What kind of files are they? mpegs and jpegs are unlikely to compress much.

Good luck.

Paul

Displaying an arrayList in a listView using the default adapter is rarely the best solution. To get full control of your display data, and to be able to refresh it after editing, requires the use of a custom adapter.
