Home at last - & Today's application

This is yesterday - I took a "down" day to actually salvage some of my vacation. I am still wonderous that we did so well. The flight home was uneventful, though I felt like I should be in two places at once - not the last time I'll feel that way!

Microsoft SyncToy v1.4 is a little free tool that allows you to keep two devices or directories "in Synch" with each other - that is, it doesn't matter what changes you make to either one, the other one will reflect those changes after each "sync." There are many such utilities, but I've found that SyncToy is the easiest to use and one of the fastest. It also does not bug you to buy anything extra, and contains no discernible spyware.

Note that this version is compatible with Windows Vista.

Suppose you have a computer at home and a computer at work, and they aren't laptops, so you can't reasonably bring them close to each other. So you have a USB ("keychain") drive, which by the way, have recently come down in price to about $30 for a 1 Gb model. You can set this up with a directory, let's call it "Portable Directory"

And on your home machine, we have a "Home" directory, and on the job, you have a "Work" directory. The object of this is to always have the two directories be equivalent, that is, always have the most up-to-date work in each.

The purpose of the Portable Directory on your keychain drive is to always have the most up to date copy of any work that you do. So therefore you will want to perform a synchronization on it using SyncToy at the beginning of your work and again just before you leave, no matter if you are at home or at work.

The SyncToy interface shows a "right drive" and a "left drive"

SyncToy can perform the following related actions between two drives, devices or directories:

Synchronize:
  • New and Updated files are copied both ways. The freshest file "wins."
  • Renames and deletes on either side are replicated on the other, so beware!

Echo:
  • New and Updated files are copied left and right
  • Renames and deletes are only repeated on the right, which means that the left drive becomes a sort of "master" drive that nothing is ever deleted from, but updates are okay.
Subscribe:
  • Updated files on the right are copied to the left if the file name exists on the left
Contribute:
  • New and updated files are copied left to right
  • Renames on the left are repeated on the right
  • No deletions are made.
Combine:
  • New and updated files are copied both ways
  • Nothing happens to renamed and deleted files
Between these five modes, any possible mode of storage can be modeled. I will just tell you that the Synchronize mode appears to me the best mode to use overall. Wow. I outmoded myself!

Here's a screen shot of my SyncToy in action. It's really amazing how fast this thing works.
