What is an XDL file?

XDL files mostly belong to SQL Server Management Studio by Microsoft. An XDL file contains a deadlock graph generated by SQL Server database management system. It contains a graph describing the cause of a deadlock which occurs due to a cyclic dependency between multiple threads or processes for one or more database resources. The contents of an XDL graph are written in Extensible Markup Language (XML). SQL Server Management Studio or the profiler in SQL Server can be used to view and analyze deadlock events in an XDL graph.

Can't Open Your .XDL File? Try These Steps

  2. Check the Header: Open the file in a text editor to inspect the opening lines.
    • Seeing <?xml or <deadlock> confirms it is an XML-based deadlock graph.
    • Seeing "PK" or scrambled characters suggests a compressed or binary format.
  3. Use the Original Software: The original program is usually required. For deadlock graphs, use Microsoft SQL Server Management Studio (SSMS). If uncertain, ask the sender.
