Description

This article provides information on how to manually create a custom File Type Association (FTA) for an application.

The FTA is created when a new file type must be registered manually for an application in which FTAs listed by XenApp are already registered.

Instructions

Complete the following procedure to create a custom FTA:

Note: In the procedure, Notepad is considered and .ext is added as a registered FTA to Notepad.

Caution! Refer to the Disclaimer at the end of this article before using Registry Editor.
  1. Locate a file that is already associated correctly with the application on the XenApp server. In this case, creating a new text document on the Desktop is adequate.

  2. Rename the extension of the file located in Step 1 to the new custom extension. For example, “Document.txt” must be changed as “Document.ext”.

  3. Open the Windows Registry (regedt32.exe) on the XenApp server.

  4. Navigate to the registry key (HKEY_CLASSES_ROOT\.txt) associated with the file identified in Step 1.

  5. Right-click the key, choose Export and save the .reg file to the Desktop.

  6. Locate the file saved in Step 5, right-click and choose Edit.

  7. Replace every instance of the original file extension with the new one (replace all entries of “.txt” with ”.ext”). Save and close the file.

  8. Double-click the file saved in Step 5 to import it into the Registry of the XenApp server.

  9. Verify that the new registry (HKEY_CLASSES_ROOT\.ext) key is listed.

  10. Verify that the new extension is registered correctly by double-clicking the file from Step 2. “Document.ext” must start Notepad.

  11. Copy the file from Step 5 to all other XenApp servers hosting the required application and double-click it to import into the Registry of the servers.

  12. Start AppCenter from the original XenApp server, right-click Farm, choose Other Tasks > Update File Types and click Yes.

  13. Restart each XenApp server where the Registry key was imported.

  14. Verify within AppCenter that the new file type (.ext) is listed as a valid File Type Association under the Content Redirection section of the properties of the application.

    Environment

    Caution! Using Registry Editor incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.
