I like this software...

I like this software... within minutes of its first fast scan, I had reclaimed around 50 gigabytes of disk space. It is a program that is both minimal and slick in use. Would I like to see some refinements in the next version? I think so. Some means to adjust or specify the colours used for each level of depth. People with poor vision may find it hard to discern the subtle colour changes from the chosen blue though to white as the indicated depth of the file changes.

I missed having a tree view to show where in the file tree the application was pointing. When selecting each folder location from the desktop view provided by this app, I would have liked to see a function similar to showing the path bar at the bottom of the OS X finder window, which is invoked from the view menu. It may eat into the clean real screen estate which is currently presented by this software but I would like to see a toggle option. With multiple large hard drives becoming more usual I feel confident that this sort of option would be used widely, if offered. My own storage currently totals 8 terabytes across 3 physical hard drives and one virtual hard drive.

Thanks to the developer for a very useful app. I can recommend it to other users.


I think I've only written one review on the app store before now but felt, after using this app, that I should say something. I have a Macbook Air 64GB - not a huge amount of storage space, especially given I have an ipad and iphone being backed up on it. I was sitting this morning with 3GB spare, unable to download software updates and wary of the fact that OS X Lion is out this month, which requires 4GB (I believe). After downloading Space Gremlin, reading some of the tips and getting to work, 30 minutes later I now have just over 40GB of space free on my Macbook Air. I've freed up 37GB of space - more than half of the total capacity!!! The visuals on the app, the speed and the simplicity are all great - I just wish they made it for other platforms. Fantastic app - download now if you feel that you need more space!!!!

Very nice app

This really is a very slick application, and it does its job well. The suggestions for the previous version (primarily to include a move to trash from the right menu button) were well made, and well implemented. After doing so the display instantly updates rather than running a re-scan. Well presented and fast (even initial scanning).

I would like to see the sections color coded, with "hotter" sections being those with a large amount of space consumed by untouched files, and potentially duplicate matching. As it would clearly take longer to scan, I might suggest that the size scan is done first, and then the "color" added as the deeper scan progresses.

All said, absolutely worth the money and great job Space Gremlin.
