Boolean. Returns true if the file exists, false if it does not exist. If filename is null, FileExists returns null.

This example determines if the file the user selected in the Save File window exists and, if so, asks the user if the file can be overwritten:
string ls_docname, ls_named
integer li_ret
boolean lb_exist
GetFileSaveName("Select File," ls_docname, &
ls_named, "pbl", &
"Doc Files (*.DOC),*.DOC")
lb_exist = FileExists(ls_docname)
IF lb_exist THEN li_ret = MessageBox("Save", &
"OK to write over" + ls_docname, &
Question!, YesNo!)
