How can I list all the files of one folder but not their folders or subfiles. In other words: How can I list only the files?
Just adding on to carlpett's answer. For a much useful view of the files, you could pipe the output to ls.
find . -maxdepth 1 -type f|ls -lt|less
Shows the most recently modified files in a list format, quite useful when you have downloaded a lot of files, and want to see a non-cluttered version of the recent ones.
