Hi

Is there anyway I can get the incoming file size using the file read node?

This value is stored in the local environment.

Code:

Offset INTEGER The start of the record within the file. The first record starts at offset 0. When Offset is part of the End of Data message tree, this value is the length of the input file.

If you want to know ahead of time what the size of the file is, you'll need to use a separate flow and a JCN to scan the directory.

You'd struggle to get that from a FileInput node, unless you're working with fixed length records.

Why do you need to know? Perhaps there's another way to achieve the requirement.

Hi Thanks for the reply. I need to know how big the file is so that in-case a 5GIG file is processed during the day I should just move it to batch and not process it right away.

If I use Jedi Knight suggestion I will only know when I read the last batch as I am currently reading one line at a time.

Put another flow in front of this one, that reads the whole file instead of a record at a time.

Use that to route files to 'batch' vs 'realtime' processing.
