Hi @gsivaprabu - welcome to the community! I’ve moved your post to Help because it is the best category for getting help.
Could you give us more information about your problem? Here are some guidelines for helpful details. 
As best as I can tell, the pre-request Script function in Postman is pre-flight - so the file is not yet loaded into memory for any file manipulation (you’ll get the path to the file on your system, but no data on the file itself).
request
{mode: "formdata", formdata: [1]}
mode: "formdata"
formdata: [1]
0: {…}
description: {…}
key: "document"
type: "file"
src: "/<pathtofile>/file.pdf"
