I've seen there are a number of different applications for OSX that lets you visualize disk space and browse the category tree as an index - JDiskReport, DaisyDisk, Disk Inventory X, etc. I would like to be able to save the disk image and directory tree that these applications generate for future reference and browsing. Does anyone know if any application of this kind allow for that? I can't find this information in these applications' online feature spec. Thanks.
