The flat file can iterate over large files processing one chunk (defined by the top level record and all of it’s childs in a hierarchical structure) at a time, so not the whole file is loaded into memory at once (Requires using a stream as input to make sense).  
Details on how to use it can be found in the Flat\_File\_Schema\_Developers\_Guide - Handling Large Flat Files.

Apart from above said…you should set [COLOR=#ff3333]“iterator” to true

for example handling large files in case TN largefile config (tspace storage)

wm.b2b.editn:getTspace (edidata- object stream)  
Repeat Step  
–\>convertToValues (iterator=true)
