Delete FSA Archiv. What happend with Dedup Files

Hello,

i have an question abaout deleting an FSA Archiv in 10.0.4. What happend or what have i to to when i delete an Archiv in the console. I test this and have problems to open files that are deduplicate. I create 2 Shares with same files EVdata01 and EVdata02. I archiv both directorys in an archiv 01 and 02.

when i delete Archiv02 which has the same files than 01. does Enterprise vault know this an let the files on storage? Or have i run fsautil or else after delete an archiv so that all Data on EVdata01 are working ?

Thanks.
