How to use DESlock+ Go on a machine without DESlock+ installed
Article ID: KB24 email a link to this article

Once a USB flash/hard drive has been configured for DESlock+ Go, it can be plugged into any machine that does not have DESlock+ installed. Depending on the operating system it may or may not automatically run the DESlock+ Go software. If the DESlock+ dialog does not appear on screen browse to the root the removable media and double click on dlpgo.exe (shown below) to launch the application.

Depending on the operating system you may also be shown the following warning dialog

DLP Go size limit warning

This occures due to file size restrictions on some versions of windows when accessing web folders (DESlock+ Go uses a technology called WebDAV) see: for more details.

The 4GB upper limit is the absoulte maximum imposed by the Windows WebClient service. It is not possible to increase the value beyond this so it is not possible to use DESlock+ Go, via WebDav, to access files greater than 4GB.

If, on this machine, access to a file which size is over 47.7 Mb is not required then you can put a tick in the 'Don't show again' check box and click 'Ignore'. However, if access to files over 47.7 Mb in size is required, click the 'Change' button and the following dialog will appear. This will require a system restart.

Once DESlock+ Go has started you will be shown the password dialog

When the correct password is entered you will then see

If viewing 'Computer' or 'My Computer' it will appear as

You may find that when you access removable media using DESlock+ Go it shows that the removable media is the same size as the local disk as shown in the screenshot below.

As stated previously, DESlock+ Go uses the WebDav protocol in Windows, this causes a descrepancy which reports the disk size of the OS drive not the removable storage when the drive is accessed. The reasons for this are covered in this Microsoft KB article - 'WebDav mapped drive reports incorrect drive capacity'.

Unfortunately this is listed as by design by Microsoft and so far we have not found any way to circumvent the behaviour.

To show the actual size of the encrypted drive, insert the encrypted drive into a machine with DESlock+ installed, right click the DESlock+ logo in the tray menu, removable media, removable media encryption, this will show you the actual disk space of the connected drive.
