ZipFile

About

TZipFile is an object that encapsulates a zip file so you can access it as if it's a filesystem. TZipFile is released under the LGPL license. TZipFile comes with a Lazarus package, so it's very easy to install it. The component is tested under Win32 and Linux_x86_32. File compression is currently not implemented although this feature is under development, so check SVN regularly. Currently only uncompressed files can be read and written to and from a zipfile.

Note: For people needing compression: TZipper reads/writes zip files and supports various compression algorithms. See paszlib#TZipper
