I can't understand what is your requirement
If you need to count files in folder
Use get files in folder activity and
Set a variables as files.count then you will get the number of files inside the forder
If you need the file path for all the files present in the folder then
After doing the above flow use for each loop and iterate through the files
Then in current item you will get the path of the file for all the files in folder
And if you need some part of the path then you can use get file path part activity
Hope this helps
