Does the finder information map file exist and contain the correct information?

The finder maintains information about files, such as the file's creator, type, location on the desktop, and icon. When the server cannot locate finder information, it attempts to generate reasonable default values for this information based on data in the map file. These values may not contain the correct information.

An AppleTalk map associates file suffixes with Macintosh applications. The client operating system uses these associations to determine which application it should invoke when it accesses a file.

To check mapping configuration, use the "tnsuffix""tnsuffix command.
