I am writing a program that downloads tar.xz files from a server and extracts them in a certain place. I am struggling to find a away of extracting the tar.xz file in the certain place. I am using Qt so a more Qt-way of doing it would be useful, but I don’t really mind.
There is no support for archives in Qt. You can either have a look at the KDE library which offers support for virtual file systems or you can use
QProcessto calltardirectly. Use-C <dir>(uppercase C) to specify the directory to extract to.[EDIT] There also is libtar (BSD license).
