Do all sliding doors come apart?

I have one that I am assuming comes apart on the bottom by tapping the bottom off. I just want to make sure they all come apart. I do not believe this is a vinyl one as there is no second screw on side of door and you can see the screw tip is facing down to bottom of door.

Thanks for the assistance.

Your patio door looks like it is a vinyl type, so I don't believe you can take it apart. Look at the related videos on how to replace a roller in a vinyl patio door since it appears that this might be the type of door you have. Thank you!
