Version Information

Auto-Mount Devices 
This function allows you to mount TrueCrypt partitions/devices without having to select them 
manually (by clicking ‘Select Device’). TrueCrypt scans headers of all available partitions/devices 
on your system (except DVD drives and similar devices) one by one and tries to mount each of 
them as a TrueCrypt volume. Note that a TrueCrypt partition/device cannot be identified, nor the 
cipher it has been encrypted with. Therefore, the program cannot directly “find” TrueCrypt 
partitions. Instead, it has to try mounting each (even unencrypted) partition/device using all 
encryption algorithms and all cached passwords (if there are any). Therefore, be prepared that this 
process may take a long time on slow computers.
If the password you enter is wrong, mounting is attempted using cached passwords (if there are 
any). If you enter an empty password and if 
Use keyfiles
is unchecked, only the cached passwords 
will be used when attempting to auto-mount partitions/devices. If you do not need to set mount 
options, you can bypass the password prompt by holding down the 
Shift 
key when clicking 
Auto-
Mount Devices
(only cached passwords will be used, if there are any). 
Drive letters will be assigned starting from the one that is selected in the drive list in the main 
window.
Dismount 
This function allows you to dismount the TrueCrypt volume selected in the drive list in the main 
window. To dismount a TrueCrypt volume means to close it and make it impossible to read/write 
from/to the volume.

Dismount All 
Note: The information in this section applies to all menu items and buttons with the same or similar 
caption (for example, it also applies to the system tray menu item 
Dismount All
).
This function allows you to dismount multiple TrueCrypt volumes. To dismount a TrueCrypt volume 
means to close it and make it impossible to read/write from/to the volume. This function dismounts 
all mounted TrueCrypt volumes except the following: 
•
Partitions/drives within the key scope of active system encryption (e.g., a system partition 
encrypted by TrueCrypt, or a non-system partition located on a system drive encrypted by 
TrueCrypt, mounted when the encrypted operating system is running). 
•
TrueCrypt volumes that are not fully accessible to the user account (e.g. a volume mounted 
from within another user account). 
•
TrueCrypt volumes that are not displayed in the TrueCrypt application window. For 
example, system favorite volumes attempted to be dismounted by an instance of TrueCrypt 
without administrator privileges when the option '
Allow only administrators to view and 
dismount system favorite volumes in TrueCrypt
' is enabled. 
Wipe Cache 
Clears all passwords (which may also contain processed keyfile contents) cached in driver 
memory. When there are no passwords in the cache, this button is disabled. For information on 
password cache, see the section 
Cache Password in Driver Memory
