When you upload a flat file from your local machine, the Analyst tool uploads a copy of the flat file to a flat file cache directory in the Informatica services installation directory that the Analyst tool can access. Contact an administrator to configure the flat file cache that the Analyst tool uses for the network path. When you choose a network path, you can specify the location to the flat file on your local machine.

You can synchronize the changes to the flat file data object if you modify the source flat file.

When you import a flat file data object, the Analyst tool infers the Numeric or String data types for flat file fields based on the first 10,000 rows.
