How to stop a flow if file does not exist

[netaware]

Hello,
I have a flow that processes hundreds of files.

On activating the flow, I would like to check for a log file first, if it exists, process the many files, if it does not exist, do not process the many files and send an email.

I do not know how to do this. Can anyone give me some suggestions?

Thanks

There is an app for this:

I tried it but i cannot get it to work with network path.

I wrote a script that is working.

But I want to stop the flow completely if the file does not exist.
