UDR File Editor

The UDR File Editor allows you to view and edit the content of UDR files. The UDR file may be of any format as long as it has an associated decoder. 

Since UDRs often contain a large number of fields, it is possible to create a UDR View to select specific fields to be displayed as columns in the UDR File Editor. See UDR Views for more information. Each UDR can also be opened in a separate dialog where all fields are available.


By default the UDR File Editor only supports input files up to size 3MB. If the file size exceeds this limit, the UDR File Editor only reads up to 3MB of the file and then stop, displaying only the read records.

If you want to support decoding of files larger than 3 MB, you need to set the Desktop property mz.gui.udreditor.limit for the corresponding Desktop. See Desktop Properties. Setting the property to yes means the 3 MB limit applies. Setting the property to no bypasses the limitation mechanism, which may potentially cause out-of-memory errors in the Desktop.

Several UDR File Editors can be used simultaneously, however, avoid editing the same UDR from several different editors, since there is no functionality to handle real-time co-authoring.

To open the UDR File Editor, open the Manage screen and click the UDR File Editor button.
