The best practice for sharing within an organization is to store the source data on a server. This ensures that any metadata that you work with on your local machine remains current. If you save a file-based data source to your local machine, the file that keeps the metadata linked to the source data looks for that data on your machine. This can be problematic if you want to share the metadata file. The linking mechanism attempts to locate the data in the same place that you stored it. To work around this, send the data source to the new user. They must either save everything in the exact same locations as you did, or edit the FSD file to point to the new location of the data source.
