Overview

QFileInfo class provides system-independent file information.

QFileInfo provides information about a file's name and position (path) in the file system, its access rights and whether it is a directory or symbolic link, etc. The file's size and last modified/read times are also available.

A QFileInfo can point to a file with either a relative or an absolute file path.

QString base = fi.completeBaseName();  // base = "archive.tar"
