Before copying or removing a directory list its contents with the command:
ls -FR
This lists any files and descends any subdirectory trees, listing their contents. For example:
ls MetaCard BLURB.txt BUGS.txt FAQ.txt README.mc metacard/
MetaCard/metacard: Makefile XCmdGlue.c XTtemplate.c XtTemplate.c mc* README.ext XCmdGlue.h XtGlue.c external.c XCmdFuncs.c XCmdNames.h XtGlue.h external.h
