Mapping a Letter Drive for Your LandFX Folder

This article provides steps for mapping a letter drive to your office's shared LandFX folder on either an office server or on a shared online location using a service such as Dropbox, Google Drive, Carbonite, etc. You may need to map a letter drive because:

  • You are installing our software for the first time.
  • You already have our software installed, and you now need to configure the workstations.
  • You moved your LandFX folder and are now unable to access your Land F/X data from CAD.


What's a mapped letter drive? It's a Windows Explorer shortcut that is assigned (or "mapped") to a specific folder – in this case, your LandFX folder. When mapping this location, you'll designate it with a single letter such as L (much like your computer's hard drive is designated as the C:\ drive).



Further information:


Due to recent Microsoft Security increases, the use of XML files (critical to Land F/X) can be stopped over a UNC path. Anything other than a direct C:\LandFX folder location should have a mapped letter drive. Using a mapped letter drive instead of a full UNC path prevents issues in CAD for a number of reasons. For one, if you decide to move the server or change the server name, it will break UNC paths (e.g., \\servername\LandFX), whereas a mapped letter drive can be simply overwritten to point to a new location. UNC paths can also cause problems with uninstall packages when the network location is no longer available.





Already have a letter drive mapped to the file server where you intend to install our software? You can use this existing letter drive as long as:

  • Each Land F/X user in your office has full read-write permission for this folder.
  • Each Land F/X user in your office has a consistently mapped drive to the LandFX folder.
  • The path to the LandFX folder does not include a space. For example, X:/LandFX and X:/AcadApps/LandFX are acceptable paths.



Step 1: Before mapping a letter drive, set up your LandFX folder

Before mapping a letter drive, make sure your LandFX folder is configured to allow:


Step 2: Map a letter drive to your LandFX folder

These steps will map a letter drive to a LandFX folder in one of the following locations:

  • A shared online location using a service such as Dropbox, Google Drive, Box, OneDrive, Egnyte, or Amazon Drive
  • An office server


2A. Download our Land F/X Drive Mapper tool.


Right-click the link below, and select Save As or Save Target As from the menu. Save the file to your desktop or Downloads folder.





2B. Double-click the LandFXDriveMapper.exe file you just downloaded.




2C. Click Browse.




2D. Browse to the LandFX folder on your server or in your shared online location. (See the examples below.)


Select your LandFX folder, then click OK.

Browsing to and selecting a LandFX folder in a shared online location


Mac users:

If you're on a Mac using Parallels, your file path will look something like \\Mac\Home\User\***username***\Dropbox\LandFX. You can browse to the location on your network, but you'll first need to have file and printer sharing enabled.




2E. Open the pull-down list and select the drive letter you want to use (example: L).



Then click Map.



Your LandFX folder will be mapped to a letter drive automatically.

Drive Mapper tool not working properly?

We've seen some issues with the Drive Mapper tool in particular with Land F/X users who are attempting to map a letter drive for a shared online folder – especially when using Google Drive (previously known as Google File Stream) or OneDrive. If the Drive Mapper tool isn't working for you, try this alternative solution.

Error messages:


  • The mapped drive could not be created. The network path was not found. (when trying to use our Drive Mapper tool) Solution



  • Network Error: The specified network name is no longer available (after clicking Map) Solution

Windows Command Line alternative function (not recommended)

In the vast majority of cases, the steps for mapping a letter drive outlined above will be sufficient – and much simpler.

Need to remove an existing letter drive?

You may need to remove a letter drive from your network because you:

  • Are no longer using that drive
  • Chose the wrong path or drive letter and need to re-create it
  • Simply want to change the mapped drive and remove the existing one


In any of these cases, follow our steps to remove a mapped letter drive.


Step 3: Once you've mapped your letter drive:

After mapping a letter drive to your office's LandFX folder, keep the following considerations in mind.


• Permissions

The paths to the Land F/X database and our default blocks are both located in the LandFX folder. To use our software properly, Land F/X users require full read-write permissions to the LandFX folder. For example, if users need to modify blocks, or create their own blocks, all this activity will take place in the LandFX folder on your server. For instructions, please see our article on Granting Read/Write Permissions for the LandFX Folder.

If you are a member of a domain, you'll need to have your network administrator modify the Active Directory to allow you to obtain read/write permission for the LandFX folder.


• Verify the Support File Search Path

At this point, you'll also need to ensure that AutoCAD knows where to look for the mapped letter drive. Follow our instructions to verify the Support File Search Path.


• Having issues mapping a letter drive using Google Drive or Google File Stream (GFS)? Do this as well.

If you're using a shared online folder with the Google Drive or File Stream service and you're having issues keeping that drive mapped, you'll need to take an extra step. Here's what to do.


Common Known Issue: "F/X CAD Cannot Function" Error



Seeing an F/X CAD cannot function without Land F/X installed correctly error after rebooting your computer, or after returning to work in the morning or after the weekend?:


We've had an ongoing issue with clients sometimes getting the F/X CAD cannot function error upon rebooting. This issue typically occurs because the user's office has a mapped drive that is not connecting correctly during the reboot, which in turn causes problems between F/X CAD and Land F/X.


To resolve this issue, use the link below to download our Disconnecting Drive Fix tool. Download the tool to a location where you can find it easily, such as your desktop or Downloads folder.





Go to the location where you downloaded the file linked above.


Locate and double-click the file DisconnectingDriveFix (or DisconnectingDriveFix.exe).




Use the menu to select the letter assigned to the mapped drive that keeps disconnecting when you reboot. Then click Next.

Disconnecting Drive Already Configured


If you see this message, it means our Disconnect tool has already been used to set up a letter drive in your office. Click Yes to add another drive to the list, or click No to replace the previous drive with the drive you've just selected.




You'll see a message that the selected drive will now be reconnected on each reboot.


You should now be able to reboot your computer and open CAD without seeing the error.

F/X CAD not starting properly? Still getting the error after completing these steps? See our F/X CAD Cannot Function error page.






How to Remove a Mapped Drive

You might need to remove an existing mapped letter drive from your network because you:

  • Are no longer using that drive
  • Chose the wrong path or drive letter and need to re-create it
  • Simply want to change the mapped drive and remove the existing one


If so, here's how:


1. Open the Windows Start menu.


Scroll down to and select the Land F-X menu option. In the submenu that opens, select Remove LandFX Mapped Drive.

Our Drive Mapper tool will have created this shortcut in your Start menu.




2. You'll be asked whether you want to remove the letter drive that's currently mapped to your LandFX folder.


Click Yes to remove the drive.
