Data dedupe - file exclusion

[tech-man]

Just looking at migrating student data to a deduped drive... should I be looking to exclude any file exts from dedupe? VHD, PST?

 

Thanks

would be good to have a list of recommended files to exclude. As it stands my DeDupe drives are purely Home and Share drives. But the .pst has me thinking, and I'd definitely exclude VHD's if they are live
