Documentation

Maximum number of working directories to be cached.

This is the size of the cache of file-name-all-completions results. Each cache entry is time stamped with the modification time of the directory. Some systems, like Windows, have unreliable directory modification times, so you may choose to disable caching on such systems, or explicitly refresh the cache contents using the command ido-reread-directory command (C-l (ido-reread-directory)) in the minibuffer. See also ido-dir-file-cache and ido-save-directory-list-file.
