Folder Snapshot Utility for Pc

I recently purchased this app for $4.99 and ran it today. I was disappointed by the experience. I had it make a snapshot of a 400 MB the app (the Sites the app in my Home the app) and a 500 MB the app (my Google Drive the app). Both times there was absolutely NO indication of what is was doing or if the action was in progress or completed, etc. I even went to check Activity Monitor to see if the app was stuck in the background or something, but by the time I did, the app was apparently done with its job and did not appear in the normal CPU-usage list. I never saw the "Progress" bar shown in screenshot #1 provided in the app description (at the time of this writing). Naturally I wondered where my snapshot was - but could not find it anywhere. It never asked me where I wanted to put the snapshot (my intent originally was to put it on an external volume so I could have an up-to-date backup of the the app on an external drive). I used the Snapshots > Show Snapshots… menu item and could see that it was in the snapshot archive, but I do not know where exactly on my hard drive it is. Perhaps I am using it wrong. I don't want to fill my drive with duplicates of large folders like my 124 GB Dropbox the app which is what I really wanted to snapshot with this app. I want to be able to "snapshot" it to an external drive - like an rsync for folders to an external hard drive. If this is what you are looking for also, this app will not provide your solution at this time.
