When you select "Save As .." you should have a window open which allows you to identify where you want to save the page and the file type. If you select a file name it will provide a folder. I suggest you select "Desktop" and leave the name as automatically selected but confirm your file type. You should then simply have the page with no folder; this can be renamed (leave the suffix if it's visible) and moved to wherever you want it kept.
