Keyfile Search Path By adding a folder in the keyfile dialog window (click
Add Path ), you specify a
keyfile search path .
All files found in the keyfile search path
*
will be used as keyfiles.
Important: Note that folders (and files they contain) found in keyfile search paths are ignored. Keyfile search paths are especially useful if you, for example, store keyfiles on a USB memory
stick that you carry with you. You can set the drive letter of the USB memory stick as a default
keyfile search path. To do so, select
Settings ->
Default Keyfiles . Then click
Add Path , browse to the drive letter assigned to the USB memory stick, and click
OK . Now each
time you mount a volume (and if the option
Use keyfiles is checked in the password dialog
window), TrueCrypt will scan the path and use all files that it finds on the USB memory stick as
keyfiles.
WARNING: When you add a folder (as opposed to a file) to the list of keyfiles, only the path is remembered, not the filenames! This means e.g. that if you create a new file in the folder or if you copy an additional file to the folder, then all volumes that used keyfiles from the folder will be impossible to mount (until you remove the newly added file from the folder). Empty Password & Keyfile When a keyfile is used, the password may be empty, so the keyfile may become the only item
necessary to mount the volume (which we do not recommend). If default keyfiles are set and
enabled when mounting a volume, then before prompting for a password, TrueCrypt first
automatically attempts to mount using an empty password plus default keyfiles (however, this does
not apply to the ‘
Auto-Mount Devices ’ function). If you need to set Mount Options (e.g., mount as
read-only, protect hidden volume etc.) for a volume being mounted this way, hold down the
Control (
Ctrl ) key while clicking
Mount (or
select
Mount with Options from the
Volumes menu). This will
open the
Mount Options dialog.
