文件管理器，或文件浏览器，是一种提供用户接口来操作文件系统的软件。多数常用操作针对文件或文件群组，这些操作主要有创建、打开（例如浏览、播放、编辑、打印等）、更名、移动或复制、删除、搜索，以及修改文件属性、设置和权限。文件夹和文件可能用文件树呈现。有些文件管理器受到网络浏览器的启发，出现像前进和后退这些导航按钮。

有些文件管理器经由协议（诸如FTP、NFS、SMB、WebDAV等）可提供网络连接。经由允许用户浏览文件服务器（像对本地文件系统一样地连接并访问服务器文件系统）或向文件服务器协议提供它自己的全部客户端实现，就可以实现如上所述标的。

A file manager or file browser is a computer program that provides a user interface to manage files and folders. The most common operations performed on files or groups of files include creating, opening (e.g. viewing, playing, editing or printing), renaming, moving or copying, deleting and searching for files, as well as modifying file attributes, properties and file permissions. Folders and files may be displayed in a hierarchical tree based on their directory structure. Some file managers contain features inspired by web browsers, including forward and back navigational buttons.
