What does Squeeze do? Well, in one short sentence: it saves you a lot of space on your (internal) HDD.
How does Squeeze do that? The guys at latenitesoft.com call their software a „background file compressor“. It runs in the background and uses the HFS compression technology that already comes with Snow Leopard.
As far as I know, Snow Leopard uses this technology exclusively for applications that come with the OS (Safari, Mail, …) and all that Squeeze does, is extending this cool OS X feature to virtually all files on your disk (well, on all files that are in folders that you chose to have compressed).
This works so good and fast, that you won’t even notice it! After the initial compression (this can take a couple of hours) you won’t even see your system performance affected. Not while new files are being compressed, not while compressed files are being accessed.
In my MacBook, there’s a 320GB hard disk installed. However, I have only about 130GB of data on that disk.
Wanna see what Squeeze did for me? 🙂
I’d love to see Squeeze compress files on external hard disks (meaning: connected via USB, Firewire, …). I contacted the developers about that. The answer was more or less, that this is, of course, possible and will likely be added to later versions of Squeeze. However, for now, this feature seems to bear some dangers – what happens when the USB plug falls out of the USB hub while Squeeze is compressing files on the disk?
My solution would be: copy the file that is to be compressed from the external HDD to the internal HDD, compress it, move the compressed file to the external HDD, remove the uncompressed file from both, the external and the internal HDD. Of course I don’t want to do that manually, Squeeze should do that for me.
Well, we’ll see how they’ll solve this problem.
If you didn’t get Squeeze via MacHeist, right now they offer it an „introduction price“ of $10. Go, get it!
