I own a video toaster and have a corrupt IFF file called "Sphere". This is included with the Toaster. Do not know how file became corrupted. I have con- tacted NewTek. They informed me that partial reinstallation was not possible. Yet I had an idea that with DOpus, I could find where the original "Sphere" was located, delete version of it on my hard drive, and replace it with original. Of course, if original came corrupted, this will not work, but worth a try, no??? Only thing that scares me is do not want to F**k up Toaster, excuse language please. Anyway, would appreciate some feedback on this. I have been very busy so I have not checked out all of the features of DOpus, but I find your program a godsend, very fair price and does so many things, it has helped me out immensely. Can DOpus compress files??? I looked for it in manual index, but could find nothing. I would like to upload Toaster framestores to Comp, but I am unfamil- iar with file compression. Have learned about extracting, have most of the archives for extraction, but need some help with compression.
