Copy folder qt c ++

How can i copy a folder to another directory?

Hi
You can use QFile::copy to copy all files to new folder.
If you need to do it recursively, Qt has functions for that too that you can combine to a working function.

@Nathan-Miguel Keep in mind that those stackoverflow solutions use recursion, which may result in (ironically) stack overflow with deeply nested directories. Also, if there's a lot of files QDir::entryList will return a large list, which might require large amount of memory.
A better solution might be using QDirIterator with QDirIterator::Subdirectories which uses resources only for one entry at a time.
