report invalid filepath

[cmhosale]

I ran the script with an invalid filepath for one of the two destinations (it was a typo), and instead of quitting the script continued with only the first destination. I would like if it reported if any of your filepaths are not correct, and if it isn't correct quit with an error message.

This was the command that ran without quitting, the second destination was the one with the typo (I forgot a slash after "372317").
