These are few things I've written over the years to "syncronize" two similar
directory trees without taking the time to copy ALL files!

Basically make the second the same as the first (copy added or changed files,
delete removed files).

This let me keep backups of large trees/whole systems "up to date" without
taking the time to copy "everything" over-and-over!

SYNC    My original DOS sync
WSYNC   Later/Simpler version for Windows
CCDIR   Interactive compare two directory trees
CHANGED Track which files have changed
RECENT  See what's changed recently
DDCCV   CopyCompareView (prob the one I use most)
DDZBK   Backup whole tree to individual .ZIPs for each subdir
ISYNC   Interactive SYNC
------------------------
Does basically the same as SYNC and WSYNC but lets you interactvely select,
view and compare the files to "synchronize".  Makes a nice way to see exactly
what is different between two essentially the same trees.

Note: To do this, ISYNC uses an internal 64k memory "segment" to store detailed
information about the selected files... so it may fail with "SegmentOverflow"
when used on very large trees!
