How do I email log files on HTC One (M7)

[dj9281]

Using file manager when I try to find a log file there's no option to attach it to an email. There's only copy and move. If I copy it will not paste into a gmail. If I move it and I search for it as an attachment with in the Gmail it does not show up with other files in a given folder. How do I send a log file by email?
