Clusters is a background file compressor, which uses FS-compression technology to transparently compress the folders you configure it to process. OS X will read those files normally, they will just take less disk space.

What's New

Version 1.7.2:
  • Fixed a couple of issues with the menu icon when running on OS X 10.9.
    • Important: Running Clusters version 1.6.x (or earlier) on OS X 10.9 may trigger a serious incompatibility problem that could cause some of your files to appear as if they had zero bytes (your data is still there, though; it just looks like it cannot be accessed). If you used an old version of Clusters in more...

Requirements

OS X 10.6 or later

Sorry, I retract that. Fixed the ACLs on ~/Library/PreferencePanes and all is working again.

I have been waiting since Dec. 20th for this company to respond to my tech support request. I can't get my serial number to register in a second account on the same machine. Supposedly, I'm supposed to be able to, but it won't work, and they won't get back to me...

I am a fan of Clusters for a long time. I tend to use up all the available space on my drives and this extends my general usability. But I have noticed false reads of the space on my main drive. Once I restart it goes back to normal but I am curious is this is an issue with Clusters or some other drive issue.

An excellent Application which saves space on my hard drive.

I think that clusters may actually be slowing down my OS (otherwise it's the space that was used up). After I re-installed my OS and apps, I noticed that *everything* was MUCH faster. I do love the idea of saving space, but not at the cost of the speed and reliability of my overall experience.

This app should run completely seamlessly in the background, with adjustable priority/speed. It also should take fewer resources while doing its job.

The places in which you'd gain the most space would be documents, pictures, and apps. Videos, archives, audio, and other extremely large files will barely get any change. (the /system and /library is also excluded).

On Average I'd say that you'd gain 10-15% more space on your hard drive. However, I would not recommend this for SSD users because this is specifically meant for a HD.

I would recommend extra storage over compressing, because if you lose that much data it's bad, and there's most likely some files on your HD that you haven't used in months. I would recommend investing in a small SSD and replacing the disc drive with it, or a 64G SanDisk class 10 SDXC card. Running the OS/apps from either is well worth an investment, especially for the new MBP or Air.


All in all, this app is really is good if one were too lazy to sort through their data or cannot afford another storage device. It's okay for students/businesses if they have no other options. If it's just out of curiosity or wanting to make the best use of your HD, it's really not worth it in the long-run.

I finally got a response after a few weeks...

According to what they told me my email had gotten lost in a sea of spam...

They worked with me and ended up releasing an update which fixed my issues. It's now working fine for me...

I have used Clusters since the days when it was known as Squeeze. No problems, no complaints - works welll in the background compressing everything I have thrown at it.

Two minor glitches/issues - the Total Savings as reported by the app is a cumulative total over time, so the longer it has been on your machine, the greater the Total is, so use this figure with caution.

The other GUI hiccup is I have a folder listed that is greyed out - it is listed as "Other" with "Savings obtained from previously selected folders" - presumably from my previous MacBook before I migrated to current MacBook. I can't delete this entry when I believe I should be able to ..

Otherwise can recommend this app - it does what is says it will do, and for me, no issues with CPU spikes etc as reported by others.

I might have considered this product, however the demo appears to be crippled because it limits you to saving a maximum of 50Mb and expires after just one hour! How on earth am I supposed to really put this product thru its paces, see how it performs, whether I encounter any issues, whether it really benefits my setup (Mac Pro with 6Tb of internal storage) and the way I work if all I get is one hour and an absurdly low compression limit?

I've heard of 30 day trials, 14 day trials even 1 day trials but this is daft.

No complaints here, great little gem. In my case, it's 60 Gb of free disk (in both my internal 320 GB HD and 120 Gb SSD).
One issue I have is about virtual machine image disks, like the one from VMware or Parallels. Should I allow Clusters to compress them?
