What is indirect file loading in Informatica?
Indirect loading for flat files In the Informatica PowerCenter, the indirect source file type option is used to load the data from multiple sources files that have the same structure and properties. The integration service reads each file sequentially and then loads the data into the target.
How do you load multiple files in Informatica?
First create a flat file with all the 10 filenames along with their path. Now select indirect option and give source file name as list. txt. Now Informatica will pick the files one by one in the same order provided in the list file and load it to target.

What is direct loading method?
Direct loading test is one of the basic & easiest test to calculate efficiency & regulation of transformer. Efficiency is ration of output power to the input power. Regulation is defined as change in secondary terminal voltage from no load to full load (keeping primary terminal voltage & temperature constant)
