Using command line parameters

Specifying a configuration file

To specify the configuration file the client should start with:

 (lightbulb) The client will use <clientname> to create configuration files, keyfiles and others with that name in the same directory, where the configuration of the first client is located.

Starting multiple instances of the client

To start a second instance of the client on the same machine, skipping the "already running" warning:

Running the client on a terminal server under different user accounts

In that case it's recommended to place a desktop shortcut for all users on that machine and extending the executable the shortcut points to with the above mentioned parameter.

Running the client on the same machine under the same user account

In that case it's recommended to combine this parameter with the one to specify a configuration file and a default folder path to use (see below), so both instances will start up using a different configuration and different default folder path. Both instances will be running on the same machine then and will be able to find each other via network broadcasts using the local loopback adapter. 



Command line parameters for folder configuration

Folders can also be created/removed using command line options.

Creating folders via command line

To create a a folder via command line:

Example for creating a folder via command line using a custom transfer mode:

(Warnung) It is recommended to NOT specify the ID during folder creation. The client will generate a random generic ID automatically, which will be used to join the folder on an other client.


Specifies the transfer mode which should be used for the folder. Example:


(Info) If not specified the transfer mode Auto Sync will be used by default.

(Info) Transfer Mode Configuration is described in a separate article in our documentation.


Specifies a script which should be executed when a new file has been successfully downloaded to the folder. Example:

dlscript=C:\Scripts\received.bat %1

(Info) Executing scripts after download is described in a separate article in our documentation. 

Specifies if the folder should automatically be backed up on the server the client is connected to. Example:
