Description
The function tests if the specified file "test1.txt" exists. If it exists, the
value true
will be returned. If it does not exist, then true
will be returned. If it does not exist, the
value false
will be returned. If the parameter would, for
example, be "C:/test1/", the function would return
false
since "test1" is a directory.
