Using tfileproperties to get size returns null Talend

asafrian1700127126 — Fri, 22 Mar 2024 06:27:06 GMT

I use tfileproperties to get the size of a file but it produces null

I have expression below

row2.size!=null?"Create XML Success, With Size = "+Long.toString(row2.size/1024)+" KB":"Create XML Success, With Size = "+row2.size+" KB"

But return null

even though the file is formed and its size is 5kb

Can anyone help me why it produces null when it should contain a value?

Ensure that you are passing the correct file path to the component. If the file path is incorrect, it may result in null values.

Hello

The result of this calculation row2.size/1024 is an integer, because the file size is too small (5 KB less than 1024), so its result is 0. You will have the exact file size with the expression:

row2.size!=null?"Create XML Success, With Size = "+row2.size+" KB":"The file is empty"
