It is a feature. In the old days of the Apollo OS two leading slashes identified a network path. In the consolidation of operating system feature sets that feature was preserved and is still possible depending upon the system. It is allowed but not required. Your system may not use the feature but others do. More recently Cygwin is making good use of it in the Cygwin environment for the same purpose. Therefore the standards say that two leading slashes are significant and are handled specially. It might be a network path. But three or more leading slashes are not significant and anywhere else in the path multiple slashes are not significant. Bob
