All the grahps in Disk Triage can be exported as either Bitmaps or Windows Metafiles. You can access this ability either via the main menu or by right clicking on any of fthe graphs - and choosing Export from the popup menu. In either case you are prompted for a file name to which to save the file.
As well - you can also export the graphs to the clipboard so that you can easily paste them into other applications like Excel and Word.
