File Extension about

Hi everyone,

I have a question about the file extension. I would appreciate it if someone who knows answer.

I’m sending screenshots below.

I want to get the name and extension of the pdf file with the “Loop>file for each file in folder” command.

But even though the extension is pdf, it appears as null. (I want to email the pdf file but it doesnt read the file.)

Where am I doing wrong and how can I fix it?

Thanks in advance
