Command Line Interface

DoxBox supports passing parameters via a command line interface.


DoxBox.exe /mount /volume <volume> [/freeotfe | /linux] [/readonly] [/drive <drive letter>]
[/offset <offset>] [/nocdbatoffset]
[/keyfile <keyfile>] [/keyfileisascii] [/keyfilenewline {CRLF|LF|CR}]
[/lesfile <LES file>]
[/saltlength <saltlength>] [/keyiterations <keyiterations>]
[/password <password>] [/silent] [/noexit] [/minimize]
[/settings <settings file>]

DoxBox.exe /dismount {<drive letter>[:] | all} [/force]

DoxBox.exe /count

DoxBox.exe /create

DoxBox.exe /portable {start | on | 1 | stop | off | 0 | toggle} [/silent]

DoxBox.exe /drivercontrol gui
DoxBox.exe /drivercontrol count [/type {total | portable | installed}]
DoxBox.exe /drivercontrol install /filename {<driver filename> | all} [/silent]
DoxBox.exe /drivercontrol uninstall /drivername {<driver name> | all} [/silent]


DoxBox has command line parameters so most operations can be run from the command line or MS Windows shortcuts.

Note on terminology

In the DoxBox GUI and documentation aimed at new users, easy to undersand words like 'open', 'DoxBox' and 'lock' are used. In documentation aimed at more advanced users (like this page) standard file system terms are used, as follows:

DoxBox Volume A DoxBox
Volume A 'Box', perhaps for a legacy app
Mount a volume Open a Box
Dismount a volume Close a Box
Flush keys for a volume Lock a Box


DoxBox was previously known as 'FreeOTFE'. The driver that handles native DoxBox volumes ('DoxBoxes') is still known as the 'FreeOTFE' driver and the name is preserved in some filenames and command line parameters.


"-" may be used instead of "/", if required.

Note: Although there is currently no option to specify which drive letter a volume should be mounted as, this may be set on any given DoxBox by selecting "Tools | Change volume/keyfile password/details..."



Count the number of open DoxBoxes. Exit code indicates the appropriate number (or error code; see below)


Create new DoxBox

/dismount {<drive letter>[:] | all}

Dismount indicated drive/all drives

/drive <drive letter>

Drive letter to be used when mounting the volume

/drivercontrol count [/type {total | portable | installed}]

Return count of drivers as exit code; total drivers present/count installed in portable mode/count formally installed. If "/type" is not specified, "/type total" is assumed

/drivercontrol gui

Display driver control dialog

/drivercontrol install /filename {<driver filename> | all}

Install specified driver, or all drivers in the current working directory

/drivercontrol uninstall /drivername {<driver name> | all}

Uninstall specified driver, or all installed drivers. Note that this takes the driver name, not the driver's filename (Important: Don't attempt to uninstall drivers which are currently in use; e.g. by a mounted volume)


When dismounting, force dismount (emergency dismount)


The specified volume is a DoxBox. If a volume type (DoxBox/Linux) isn't specified, the user will be prompted for this information.

/keyfile <keyfile>

Keyfile to be used when opening a DoxBox. Only valid when opening DoxBoxs


Only valid when mounting Linux LUKS volumes. If this flag is specified, the keyfile will be treated as containing ASCII password. Otherwise the keyfile will be treated as containing binary data. Default is to treat as binary.

/keyfilenewline {CRLF|LF|CR}

Only valid when mounting Linux LUKS volumes. If /keyfileisascii is specified, the first newline found in the keyfile will be treated as an EOF. This option specifies what constitutes a newline. Default is "LF".

/keyiterations <keyiterations>

The number of key iterations

/lesfile <LES file>

File from which to read Linux encryption settings from. Only valid when mounting non-LUKS Linux volumes


The specified volume is a Linux volume. If a volume type (DoxBox/Linux) isn't specified, the user will be prompted for this information.


Mount indicated file/partition


Minimize main window when run


Indicates there is no CDB stored from the offset specified by "/offset". Only meaningful when both "/offset", "/freeotfe" and "/keyfile" are used.


Normally, when run with command line parameters, DoxBox carries out the requested action and exits. Specifying this parameter will cause DoxBox to continue running

/offset <offset>

Use specified offset when mounting. This may be specified using GB/MB/KB units, or with no units for an offset in bytes (e.g. 5GB or 5368709120 for a 5GB offset). Note: If the value used for the offset has has a space in it, it should be surrounded by quotes (e.g. "10 GB" or 10GB are both valid)

/password <password>

The password to be used. It is not recommended that this is used; particularly in shortcuts, as this would involve storing your password in plaintext such that anyone can read it!

/portable {start | on | 1 | stop | off | 0 | toggle}

Turn on/off portable mode


Mount the volume readonly


Use specified file for program settings, instead of normal settings location


Can be used when installing/uninstalling drivers and changing portable mode to suppress dialogs, and also when mounting a volume to prevent the password entry dialog showing

/saltlength <saltlength>

The length of the salt (in bits)

/volume <volume>

The volume filename/partition to be used. When using a volume file, this should be set to the full path and filename of a volume file. Partitions should be specified in the form: "\Device\HarddiskX\PartitionY", where X is 0 based, while Y starts from 1 to indicate a particular partition, or 0 to indicate the entire disk.


Important: If the volume filename has any spaces in it, then it should be enclosed in double quotes (").


Note: Under Windows Vista, the "install" and "uninstall" options require DoxBox.exe to be explicitly "runas" an account with administrator privileges, if not being executed from a process which has already been escalated; see examples below. The "/portable" will automatically escalate to administrator privileges, if required

Exit Codes

When run at the command line, DoxBox will terminate with one of the following exit codes:




Exit code Meaning
0 Success
100 Invalid/unrecognised command line
101 Unable to connect to FreeOTFE driver; check driver is installed or portable mode is started
102 Unable to mount volume
103 Unable to dismount volume
104 Unable to start portable mode
105 Unable to stop portable mode
106 The requested operation requires administrative privileges
999 Other error

C:\ownCloud\username\LiberKey\MyApps\DoxBoxPortable\DoxBox.exe /mount /linux /volume C:\ownCloud\krice\LiberKey\MyDocuments\LUKSbusn\busnprsn.vol /drive P:
It may be due to the LUKS volume being created by EDS on Android. What's used to key off of whether or not it Linux or LUKS? Could I take a hex editor and check to see where things are not matching up?
