.PP
QDirStat can read its information from cache files. This is a lot faster than
reading all the directories in a directory tree and obtaining detailed
information (size, type, last modification time) for each file and directory
with the opendir() / readdir() and lstat() system calls for each individual
file and directory.
.PP
QDirStat can also write those cache files ("Write Cache File..." from the
"File" menu), but the whole point of cache files is being able to do that in
the background when the user does not have to wait for it \- like in a cron
job running in the middle of the night. QDirStat itself cannot be used to do
that because it is a KDE program and thus an X program that needs access to
an X display \- which cron does not provide.
