DIALOGLINK AND NORTON UTILITIES: CLEANING UP AFTER COPY-PROTECTED SOFTWARE Peter Brueggeman, Scripps Institution of Oceanography Library, Univ. of Calif. San Diego, La Jolla CA 92093 Copy-protected software like the first version of Dialoglink usually create hidden file(s) on your hard disc as part of the copy protection scheme; you cannot see these files using the DOS DIRectory command. DOS also places two hidden files of its own on your hard disc, named IBMBIO.COM and IBMDOS.COM. Hidden files are unerasable/undeletable and may become permanent residents on your hard disc after deinstallation or erasure of copy-protected software. Thus you could be accumulating and losing some disc space to unwanted hitchhiker files. Several software are capable of displaying a directory of all the files on your hard disc including the hidden files and then manipulating or erasing them. Software of a category called "DOS shell" usually provide this capability e.g. Keeptrack Plus and One-Dir Plus. DOS "utility" software usually can do this e.g. Norton Utilities. Norton Utilities is an inexpensive software compendium with a variety of disc maintenance software. Norton Utilities is famous for its ability to find files that you accidentally erased. When a file is erased, it remains on your disc and only the location pointer to it was erased; with Norton Utilities, you can find this erased file. Norton Utilities has software to assist hard disc users hunting for hidden files. One feature, "File Attributes", can identify and change a file from hidden file status to normal status for subsequent erasure. "File Attributes" can also be used to change a normal file to a read-only status to protect against accidental erasure; this is a nice feature to protect software from accidental erasure by clumsy users. Another feature, "Wipefile", can also erase hidden files. Read the manual carefully before attempting these activities. The first release of Dialoglink was copy-protected and created a hidden file on your disc's root directory called BBCBDADB.RO; it may still be there taking up 128 bytes of disc space even though you are now using the unprotected version of Dialoglink. Other copy-protected software that you have removed may have left ghosts behind. Obviously you should not be erasing hidden files unless you are sure how they arrived. Norton Utilities should be used for disc directory inspection before and after software installation or deinstallation, particularly of copy protected software; you need to monitor what files are being copied to or removed from your disc. Regular disc directory inspection will avoid future frustration with mystery files on your hard disc. BQ: COMMENT FROM PETER BRUEGGEMAN RE: DIALOGLINK DIALOGLINK's features work well for most general telecommunications needs with one major deficiency. DIALOGLINK's uploading feature is designed specifically for database searching; it uploads files/search strategies line- by-line to systems with a consistent system prompt like Dialog's question mark, STN's arrow, or BRS', SDC's and NLM's colon. How about the additional capability to upload files in their entirety (not line-by-line) so that Dialoglink could be used for file transfer needs like microcomputer-to- mainframe communication? DIALOGLINK should expand and generalize its mission and provide more general telecommunications capabilities. Why learn two telecommunications software when one could do it all and better?
