You can change the file path to a referenced DWF file or search for a DWF underlay when it is reported as not found.
When you open a drawing with an attached DWF file, the path of the selected DWF underlay is displayed in the External References palette under Found At in the Detail list. The displayed path is the actual path where the DWF file was found. The path where the DWF file was originally attached is displayed under Saved Path.
To locate the DWF file, the program searches the following paths and folders in the following order:
If you open a drawing that contains a DWF file that is not in the saved path location or in any of the defined search paths, the External References palette displays Not Found in the Status column of the File References list, and the Found At entry is blank in the Details list.
You can remove the path from the file name or specify a relative path by manually editing the path in the Found At box or by clicking [...] at the right side of the Found At box. This opens a Select DWF File dialog box.

When DWF files are used as underlays, there is an added level of referencing that occurs beyond the name of the DWF file. You also specify the sheet that is attached as an underlay. When altering paths, it is possible for a DWF underlay to be reported as not found if the new path is set to a DWF file that does not contain the same sheet name as the originally referenced file.
