Sonar is a security tool that reports file change activity on your hard drive in real-time. It can show you every time a program changes a file on your hard drive. Sonar can be useful for several purposes:
Run Sonar before installing a new program so you can see exactly what gets installed. Then you can remove it later if necessary.
Use Sonar to troubleshoot Spotlight-related slowdowns on your computer. Sonar will show you highly active files that you might want to consider adding to the Spotlight exclusion list to avoid frequent re-indexing.
Developers can use Sonar to monitor how frequently their software writes to the hard drive. Developers can use this information to optimize their program's hard drive usage.
This review was originally posted on VersionTracker.com. Sure...it's kinda like fs_usage, but a lot more user friendly. fs_usage just scrolls away...or you can pipe it to a file. But Sonar is great as it gives you just the pertinent information in a real-time window. Still a bit of French lingering in the App menu, but it's pretty obvious what does what by location.
This review was originally posted on VersionTracker.com. I am thrilled with Sonar. Sonar gives me all the information I need on all the file activity of my hard drive. It is great for recording what files an Installer creates on your hard drive when you install a new application. You will be amazed at the number of files some applications install on your hard drive.
It is great for finding those hidden files that an application creates to determine when your trial software has expired. ATTENTION: I am in no way promoting cheating a developer out of his payment for all his hard work. All developers should be rewarded for their effort and hard work developing software. However, some time the demo time period is inadaquite or a new version may come available but the trial from the old version prevents you from trying the new version.
