Black (Version: 1.40) is a no install, lightweight and less than 100KB unzipped freeware file manager. It is two pane and only supports a subset of features common to most file managers but at its size it’s a reasonable option.
Its basic features are copy, move, rename and delete. The rename operation can be applied to a group of files. This requires choosing the files by selecting them all (the red icon) or by right clicking a set – which turns the file names red. Rename rules include increment, counter, extension, size, time, date and case.
The program’s search tool is not the fastest and seems to only find exact matches, including extensions, by default. See images below for search results when I searched for ‘homer’.
It includes shortcuts to few systems folders and the command prompt.
Black should run on all Windows versions.
