VFSExplorerImpl.cpp@ 26550

Last change on this file since 26550 was 25860, checked in by vboxsync, 15 years ago
Main: cleanup: get rid of VirtualBoxBaseProto, move AutoCaller/Span* classes out of VirtualBoxBaseProto class scope and into separate header; move CombinedProgress into separate header (it's only used by Console any more)
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`
