I have finally gotten around to posting a couple of utilities that I have used for years. They are very useful for doing backups. ARCHIVE destpath[filename] destpath Drive and path filespec File name (wild cards supported, defaults to *.*) This program copies files from the default directory to the path specified, but only if the files also exist on that path and have an older date and time. Example: ARCHIVE a:*.c Copy from the default directory to a: all the .C files that exist on a: that are newer. ARCHIVE a: Same as before, but all the files. UPDATE fromspec [destpath] fromspec Drive, path and filename (wildcards supported) destpath Destination drive and path (defaults to current directory) Copy files from fromspec to destpath, syntax is just like the COPY command. Works just like the COPY command, except if the file exists on destpath, and it is not older than the one from fromspec, it is not copied. Example: UPDATE a:*.c \source\bvc These programs are mostly useful for making backups. I do not like the Microsoft backup programs, with their undocumented file formats and the reports of many people losing their data. These programs also use the date and time stamp of a file, not the archive bit in the directory. I think using the date and time is more appropriate. The programs are also very tiny and will fit in the corners of most disks. Archive and update are analogues of each other. Archive comes in real handy when you have a directory on your hard disk that has more sources than will fit on one floppy. First, you copy over onto multiple disks the files you want backed up. Then, at the end of each day, you insert each disk in turn and type archive a: [F3 for all subsequent disks] Backing up is very quick, since usually only a small minority of the sources got changed. Anyhow, here are the programs: begin 644 archive.com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
