Compressing the contents of a directory

[gbook]

I'm writing a bunch of files to a temp directory, and then compressing that into an archive. With your amazing help, my program is able to write zip files :-)

So, I'm able to use bit7z to zip a temp directory, for example /tmp/H6Mv5yYOMTk7FwO7LwMy, but when I open the zip file, it looks like this

   Date      Time    Attr         Size   Compressed  Name
------------------- ----- ------------ ------------  ------------------------
2024-05-08 13:32:02 D....            0            0  H6Mv5yYOMTk7FwO7LwMy
2024-05-08 13:32:01 D....            0            0  H6Mv5yYOMTk7FwO7LwMy/data
2024-05-08 13:32:00 D....            0            0  H6Mv5yYOMTk7FwO7LwMy/data/S0934URS
2024-05-08 13:32:00 D....            0            0  H6Mv5yYOMTk7FwO7LwMy/data/S0934URS/1
2024-05-08 13:32:01 D....            0            0  H6Mv5yYOMTk7FwO7LwMy/data/S0934URS/1/8
2024-05-08 13:32:01 D....            0            0  H6Mv5yYOMTk7FwO7LwMy/data/S2911QUP

How can I compress the contents of a directory without including the parent directory in the zip file? I want to retain the data/S093URS/etc directory structure as well, so I basically want the root of the zip file to contain the data directory.

BitArchiveWriter provides an addFiles method that does exactly what you need.
It takes a directory path, a wildcard filter string, and a boolean parameter for enabling/disabling recursive inclusion of files inside subfolders of the directory.

BitArchiveWriter archive(lib, BitFormat::Zip);
archive.setUpdateMode(UpdateMode::Update);
archive.addFiles(dir.toStdString(), "*", true); // instead of addDirectory
archive.compressTo(archivePath.toStdString());

That worked. Thank you!
