of noice. nnn has several additional features to provide a more complete file managing experience. Its goal is to provide file managing operations while using a minimal memory footprint and very optimized performance, as it uses low-level functions to access the file system and keeps the number of reads to a minimum, allowing it to perform well on

. As the base program follows a minimal design philosophy, additional features and functionality are available via user plugins.

Operation

Each instance of nnn provides 4 contexts, or commonly referred to as tabs, which allow you to browse multiple directories within the same instance. From within nnn basic file operations such as adding, duplicating, moving, removing and renaming files are available. Additionally it provides functionally for mass file renaming and mounting remote drives via
