Q: Can I set the zoom to a certain distance and have it take the picture at that zoom every time?

In the manual it says:Digital Zoom: In the digital zoom panel, you can zoom in or out to include/exclude your surroundings. Click back to 100% button to make your image restored to the original size. Hope that helps.

Q: how does this cam focus

The focus ring on my camera turns about 4 complete turns. While looking at the camera lens, with the ring fully counter clockwise we will call that zero turns. At 1/2 turn clockwise the camera will focus close to the lens. At 1 1/2 turns clockwise it will focus about an inch in front of the lens. At 2 1/4 turns clockwise it will focus at about 1 1/2 feet. As you continue to turn the lens clockwise you will be able to focus at greater distances. I have been able to focus at objects across the street and the focus looks good.

Q: How Can you change the file location on your computer for video ?

With the camera software active, click on the lens icon at the upper left (you should see an image) , then click on the camera icon on the left side. The bottom portion of the main screen will show the default location for saving photos. Highlight that and change it to the location you want. Click on "Photograph" near the top of the panel, click on "saved" and it should save the photo to the location you specified.
