Reading, creating, and manipulating file archives
KArchive provides classes for easy reading, creation and manipulation of "archive" formats like ZIP and TAR.
It also provides transparent compression and decompression of data, like the GZip format, via a subclass of QIODevice.
If you want to read and write compressed data, just create an instance of KCompressionDevice and write to or read from that.
If you want to read and write archive formats, create an instance of the appropriate subclass of KArchive (eg: K7Zip for 7-Zip files). You may need to combine this with usage of KCompressionDevice (see the API documentation for the relevant KArchive subclass for details).
