ido: Working Directories
1.2 Working Directories
=======================
“Working directories” are directories where files have most recently
been opened. The current directory is inserted at the front of this
‘ido-work-directory-list’ whenever a file is opened with ‘ido-find-file’
and other file-related functions.
-- User Option: ido-max-work-directory-list
This user option specifies maximum number of working directories to
record.
-- User Option: ido-max-dir-file-cache
This user option specifies 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 MS-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’
(usually ‘C-l’) in the minibuffer.
