We have a list that does a lot of file-serving and we regularly back up files stored on this list by running a routine that looks at the 'listname FILEID' file. However, we just noticed that if a file is removed from the filelist, it remains in the FILEID file (and, causes our backup routine to generate error messages because it tries to backup nonexistant files). It would seem reasonable, at first glance, that when a file is deleted, all references to it are deleted as well. How does Listserv clean up the * fileid files? Or do they just continue to grow and grow over the list's lifespan? Peter Molnar
