Discussion
One of the nice features of the Quota Entries application is that you can drag and drop entries in it to a spreadsheet application like Excel. Simply highlight the entries you're interested in and drag them to Excel. You can also copy and paste them using Ctrl-C and Ctrl-V.
If you've enabled compression on a volume where quotas are also enabled, you may actually see quota usage increase compared to the same volume without compression. See MS KB 320686 for more information on this issue.
