It's more complicated than this. The string is used twice, but it has a different meaning. In one case, it is the name of a file found online, and in another case it is a name of a local file. The local file name is used in many places, so I replaced it with a constant. The online file name occurs only in one method, and I have left it there (it is like status.txt in this sense). I have also moved a lot of other string generating code to a central location in WmfDumpFile, since the online dumps, the local dumps, and the dump manager have shared assumptions on how directories and filenames are called.
