Qt 文件目录操作

QDir 类提供访问系统目录结构

QDir 类提供对目录结构及其内容的访问。QDir 用于操作路径名、访问有关路径和文件的信息以及操作底层文件系统。它还可以用于访问 Qt 的资源系统。

Qt 使用“/”作为通用目录分隔符，与“/”在 URL 中用作路径分隔符的方式相同。如果您总是使用“/”作为目录分隔符，Qt 将转换您的路径以符合底层操作系统。

QDir 可以使用相对路径或绝对路径指向文件。绝对路径以目录分隔符开头(在 Windows 下，可以选择以驱动器规格开头)。相对文件名以目录名或文件名开头，并指定相对于当前目录的路径。

下面是QDir的一些常用方法：

  1. 构造函数：QDir(const QString &path = QString())
  2. 判断路径是否存在：bool exists() const;
  3. 判断是否是文件：bool isFile() const;
  4. 判断是否是文件夹：bool isDir() const;
  5. 获取当前路径：QString absolutePath() const;
  6. 获取文件名：QString fileName() const;
  7. 获取文件目录：QString dirName() const;
  8. 获取文件大小：qint64 size() const;
  9. 获取文件的创建时间：QDateTime created() const;
  10. 获取文件的最后修改时间：QDateTime lastModified() const;
