- CLOANTO DIRDIFF V. 5.1
-
- DirDiff is a powerful tool to scan, compare, synchronize and replicate
- files. It was originally designed for internal use at Cloanto for backup
- management and to simplify the maintenance of software master disks. Over
- the years, new features were implemented, the file comparison engine was
- enhanced and a graphical interface was added.
-
- DirDiff can be used to compare (and optionally update) two disks. Several
- options can be set to finely tune this process.
-
- DirDiff can be used to copy some files from hard disk to floppy, then use
- the floppy on another computer (for example at home), and from time to
- time automatically move the files which have changed to whichever medium
- contains the older version.
-
- DirDiff can be used to compare bootable disks against new versions of the
- Amiga Workbench disks. It can selectively compare only the files used in
- both disks, skipping icon files if desired. So only messages regarding
- relevant files are generated. If desired, DirDiff can upgrade the system
- files on work disks in the same process.
-
- When copying tens, or hundreds of Mbytes from one device to another,
- errors are more likely to occur and pass undetected than with normal,
- interactive use. Using DirDiff, at Cloanto we discovered faulty I/O
- configurations which caused only one or two bytes out of 100 million to be
- corrupt. We now always use DirDiff after each step in the preparation of
- master disks, both for floppy disks and for CD-ROMs, to make absolutely
- sure that no errors have occurred. When it finds certain errors, DirDiff
- does an additional check to make sure that the storage medium gives
- consistent results. It even double-checks the RAM locations it uses.
-
- DirDiff is an invaluable tool to back-up a hard disk to a slower device,
- such as a magneto-optical disk, because it can copy only the files which
- have changed. Results can be achieved faster and in a less
- resource-consuming way. To make the process bullet-proof, the source
- directory can be locked, and differing files can be force-copied from hard
- disk to the optical disk even if they have an older date. Files from older
- backups which become unused can be deleted in the process. The combined
- use of these functions can deliver identical copies at a fraction of the
- time a standard "Copy" procedure would normally require.
-
- DirDiff can detect even subtle differences between two items, such as a
- directory renamed from "WBstartup" to "Wbstartup". Before DirDiff reports
- that two directories are identical, it checks not only the contents, but
- also the attribute bits, file comments, dates and exact names of all
- items.
-
- DirDiff can scan a directory or disk and give an electronic signature (for
- example "DD5-A89CE287"), derived from the contents of all files. This
- short code can then be used to refer to a particular disk or product
- release without detailing the entire contents. For example, two distant
- offices which want to verify if they have the same version of a disk can
- execute DirDiff separately, and then check the signature in a phone call
- taking only a few seconds. Or the signature can be used as a reference in
- a licensing agreement, as a confirmation of what is being licensed.
-
- DirDiff includes additional checksum capabilities, and features such as
- clearing of unused blocks on a device (useful when it is desirable that
- others do not "undelete" data on a medium which was considered safe to
- give away).
