How can I zip a file through QT?

Question

C++ / C#

Hello, there is a task, you need to archive documents using QTCreator, and then get the size of the archive.
It is necessary to use compression methods for rar and zip: high-speed, normal, maximum, as well as self-extracting archive. (the files will be both .txt and .bmp).
I tried using qzipwriter, but there, as I understand it, there is no way to set compression methods.
Is there any library that can help with this? or ready-made examples?

Answer 1

using QTCreator

BUT?
On the topic - it is much easier to use the built-in archiver (we just pass the necessary keys to the zip or rar program), but this requires that the archiver be installed in the system.
