Disk Xray Lite

Disk Xray Lite, the free, little brother of Disk Xray, is a disk usage statistics viewer, duplicate files and folders finder and cleanup tool for OS X.

It performs three fundamental functions, and it performs them extremely well. It also provides you maximum security, restoring all files if you removed something accidentally.
Disk Xray Lite differs from Disk Xray with the following limitations: Duplicate files finder - view mode only Duplicate folders detection - not available Only one window can be open at a time Splash screen at startup
Disk Xray Lite is discontinued. It is still available for download, but will no longer be supported. It is replaced by Disk Xray
