When all of the SysIsFile* API's were added, an oversight was adding a generic API that simply tests for existence no matter what type of object it is.
Should not be a hard API to add. As I recall, all of them test for existence AND a specific attribute. This API should only test for existence.
Maybe SysExist / SysDoesExist for the API name?
Could this one be squeezed into the v4 release?
