How to Use Power Automate Flow Conditions

Thanks very much for this video tutorial. This is very helpful and greatly appreciate your time in sharing your knowledge. I'm a new PA user and quite enjoying my learning path watching video tutorials.
Question: Wouldn't it be better or would it make a difference if you put the condition action before the apply to each? In addition, how is using initialize variables play a part? Thanks again for your time and would be awesome to see examples when you have time.

Many thanks. Very useful especially for the signature logo which is interpreted as an attachment file, too. Very difficult to find a solution for that..until now. Very good explanation for how to use a condition (e.g. Attachment name <contains> xyz.pdf).

Many thanks for this my friend!!! this is exactly what I was looking for!!!

Microsoft changed the interface for the condition control and I don't know how to use it.

I though this would be a video specifically about the condition control, its labels, and everything about it, not the if yes or if no sections that come after it. Not useful.

This is a great tutorial. I got the file to copy to the sharepoint directory but the resulting file is empty. It's an excel file that says NULL in A1 when I open it.

I have been looking for this exact process…followed it the same 100%, but I create attachments for all files (ex: signatures), not just the one I want. Conditions seem to be irrelevant. Am I missing something?
