TOM STEIN  This is definitively the best software of this kind I ever had in my hands. It does not just put a dot in front of the name. I'm comfortable in using the terminal and I was not able to access my hidden folder without using all my tricks. Yes, a hacker may access your hidden folders, but a Unix amateur with some knowledge certainly not. When it comes to encrypted disks, even a hacker has no chance.

I love the iPhoto feature. I can now hide my adult photos library and every time I close the software and someone else opens iPhoto again my public iPhoto library is presented instead.

You can do all this with the terminal but not within seconds and with Ghost Sphere you never omit to type a command to ensure that you get no surprise once someone else uses your computer next time.

Greetings from Germany.

DARUKARU  SetFile -a V (file/folder)

Congratulations, you just saved ten dollars. Put your stuff in an encrypted disk image if you really think the bad guys are out to get you.  
(Version 2.0.2)

BICHUFO  I've PURCHASED and tried this. It works great. The Vault is saved with a dot and a filename. So what if you can go into term and see it? Or from Spotlight. It is encrypted and there is nothing you or whomever steals your file can do with it! Can't get to the stuff inside the file.

What's with the nagging thing? It is only $10! Cheapskates! You guys should move to a FOSS OS and/or roll your own.

AMBERV  Five words to the developer: Learn to write a demo!

Oh, and putting a dot in front of the name is just about the most insecure way to hide something that I've ever heard of. You know, UNIX just had that system to keep non-essential files out of the way when you scan a directory. It's just one flag away from being revealed.

LARS55  The FREE app. "Disappear" does quite a nice job at hiding one's secret folder and its contents. Tried out Ghost Sphere and must agree with everyone else, the nagging "Register Now" is more than nagging. It's downright irritating. Why pay for an app. when a free does the same job?

LIN.WEN  Since I downloaded AppZapper, I'm trying out so many more apps than I would have. After reading the review about the annoying nag messages from one of the reviewers here on MU, I thought, "Hmm.. how annoying can it be?"

It is annoying. It seemed like each action I took to try the features of this app triggered a "WARNING - YOU NEED TO REGISTER THIS APPLICATION"

Who knows, it might be useful. However, I'm a Mac user. I'm unwilling to pay for a non-sexy app.

Zap!

GRYPHONENT  GhostSphere is unfortunately in the same mold as Apimac’s Secret Folder. Don’t be fooled in believing that GhostSphere uses an “advanced way to hide folders” and employs a “448 bit military strong encryption“ in doing so. GhostSphere might achieve the latter when creating a disk image, but so are better freeware apps out there (Secret Service, Hide Safe), and in demo mode the “vault feature” is deactivated.

Let’s look at the standard feature of hiding folders instead: generally all GhostSphere does is putting a “.” in front of the folder, thereby making it invisible. The folder is not moved and still there... which means, that by making invisible items visible it will be revealed. Even in invisible mode Spotlight was right on the spot in finding files within the “hidden folder.” So much for the “Spotlight safe guarantee” (probably only true when the folders are encrypted on a disk image, but this should be clearly stated by the developer).

HARDCAT  I'd like to try this, but the demo is so in your face that it is not possible. When the application launches a message about the limitations of the demo and encouragement to purchase it are displayed. No problem, I read this and fully understood it. One of the limitations of the demo is that it quits after just 3 Mins!

Well I can accept that, but everytime I tried to do something... like hide a file! the dam demo reminder box pops up and is displayed for several seconds.

Like I said I read and understood it the first time. Anyway with this message eager to pop up and prevent me actually trying the software out, I think I actually just tried out their demo message box.. Great idea guys!....

I wonder what the software actually does and if It would suit my needs?

TREADMAN  Does exactly as advertised, with no glitches. For $10 it's hard to beat.
