TROUTNC  developer's comments appear to indicate this app does not do full (2-way) synchronization which results in updated equivalent directories.

Seems to be a major short-coming in a synchronization application.  
(Version 2.1)

TROUTNC  A neat little app that does what it says it will do...if the window is in front.

What I would prefer is an app that does this via drag and drop onto an icon in the menubar or dock. A simple drag and drop would toggle visibility of the dropped items, and an option-click would toggle "show hidden files in finder."

Thanks to the developer.  
(Version 1.1)

TROUTNC  I purchased this app and now wish I had not.

The reason:

Just 3 or 4 months after purchasing v5.6.1, this new version appeared. Satori has offered no upgrade policy for me to move up to the new version, and I refuse to purchase the same app twice.

I believe this slights people such as me who have supported the upgrade process. I emailed Satori Publishing months ago and was told an upgrade policy was forthcoming. But I have not seen any evidence of any effort to follow through on their part.

I suggest that no one further support such unscrupulous developers.  
(Version 6.8)

TROUTNC  I've been a DiskWarrior user since I first owned a mac. It was high priced but it worked. That was in the days of Mac OS 6, 7, 8, and 9.

I also have TechTool Pro and Drive Genius. And TTP saved my bacon many times. But that was pre OS X.

Under OS X 3 and now 4, I have NEVER had need for any of them. Give Alsoft another 50 bucks? I don't think so. Good backups and OS X are all I need.  
(Version 4.0)

TROUTNC  I've used some tremendous freeware and shareware for many years. Never offered a review before.

Can't be quiet about this one. IMHO, the best app, doc, and folder launcher available for OSX at ANY price.

Assign a unique command and launch it or bring it to the desktop with a quick command-key sequence followed by the first few characters of the command you gave it.

EXAMPLE: Control-x to trigger command state, followed by typing "syslib" to open the System/Library folder on your desktop. You only need enter as many characters as necessary for the command to be unique.

One CAUTION here: Be sure and set recursion to NONE before launching a folder, or every item in the folder will try to open when you mount the folder.
