Dir function lists the files and folders in current directory.
The argument ‘my_folder’ you mentioned should be a directory path, either absolute or relative.
For example, if you are in the path
C:/demo/my_dir.
then following both are valid usages
dir('.')
dir('C:/demo/my_dir')
If you try it from parent directory i.e. C:/demo, you can pass relative path also
dir('my_dir')
You can also pass a variable which contains the valid path
dirpath='my_dir'
dir(dirpath)
Hope this will be helpful to you

I suspect the OP was trying something like this:
my_dir='C:\demo';
dir my_dir
Luckily the command syntax is getting less common (except with axis and hold, etc), so this problem is getting less frequent.

dir(.) is no valid Matlab syntax. Better: dir('.').
Avoid using "path" as name of a variable. This is not an error at runtime, but during debugging shadowing the important function path() might have very strange side effects.
