Concept
File manager
Summary
A file manager or file browser is a computer program that provides a user interface to manage and folders. The most common performed on files or groups of files include creating, opening (e.g. , playing, editing or printing), renaming, , , and searching for files, as well as modifying s, properties and . Folders and files may be displayed in a hierarchical tree based on their directory structure.
Graphical file managers may support copying and moving of files through "copy and paste" and "cut and paste" respectively, as well as through drag and drop, and a separate menu for selecting the target path.
While transferring files, a file manager may show the source and destination directories, transfer progress in percentage and/or size, progress bar, name of the file currently being transferred, remaining and/or total number of files, numerical transfer rate, and graphical transfer rate. The ability to pause the file transfer allows temporarily granting other software full sequential read access while allowing to resume later without having to restart the file transfer.
Some file managers move multiple files by copying and deleting each selected file from the source individually, while others first copy all selected files, then delete them from the source afterwards, as described in .
Conflicting file names in a target directory may be handled through renaming, overwriting, or skipping. Renaming is typically numerical. Overwriting may be conditional, such as when the source file is newer or differs in size. Files could technically be compared with checksums, but that would require reading through the entire source and target files, which would slow down the process significantly on larger files.
Some file managers contain features analogous to web browsers, including forward and back navigational buttons, an address bar, tabs, and a bookmark side bar.
Some file managers provide network connectivity via protocols, such as , HTTP, , SMB or WebDAV.
