Vfp 5.0a SP3

In HELP for DELETE FILE, it says under Remarks:

"The file you want to delete cannot be open when DELETE FILE is issued. The file name must include a path if it is on a different drive or volume, or in a different directory or folder from the default, and the file name extension must be included. The file name cannot contain wildcards."

… but when my default is on drive C: and I issue the command "DELETE FILE D:\Temp\xxx*.*", all files in D:\Temp matching xxx*.* ARE successfully deleted. As it turns out, this is what I want to happen. I do have concerns, though, as the documentation seems to say that this capability is not supported.

How safe am I to rely on this capability?
