Preserve attributes for local copy/move (slower): If checked, Krusader will try to preserve all attributes (time, owner, group) of the local files according to the source file depending on your permissions.

Automount filesystems: this makes Krusader try to mount a file system before entering it. For example, if you click on /mnt/cdrom (and /mnt/cdrom appears in /etc/fstab as a mount point), Krusader will check if it is mounted. If not, it will try and mount it for you and then enter, so that you would see the contents of your cdrom. Note, however, that Krusader will NOT unmount when exiting /mnt/cdrom.

Do not use KDE media protocol for the Media button (if it is buggy or missing): If checked, Krusader will not use KDE media protocol for the Media button. Choose this when the media protocol is buggy (in some older KDE versions) or if you have no kdebase package installed on your system.

MountMan will not (un)mount the following mount points: If you have file systems that you do not want to accidentally unmount (or mount) then enter a list of mount points separated by commas (e.g. /, /boot, /tmp) and MountMan will not try to (un)mount them.

Icon Cache Size: Krusader uses an icon cache, so it will not have to reload icons that have been used before. Of course, as the cache grows bigger, it can store more icons and further speed operations, but the memory footprint of Krusader will become bigger.
