About the LoadFromFile and LoadFileSet Utilities
In addition to the demonstration data that PTC provides, you may also have legacy data that you would like to add to the Windchill database. PTC provides two utilities to load legacy data:
LoadFromFile—Loads a single, legacy data file into the database
LoadFileSet—Loads multiple data files
The load utilities process only XML files. You can use the CSV2XML utility to convert CSV files to XML formatted files.
For more information about these utilities, see Loading Legacy Data Using the LoadFromFile and LoadFileSet Utilities.
