I have a list of documents, some of which are unique and some of which are duplicates (duplicate means same hash value). The duplicates, however, have different dates and times depending on when they were saved to an individuals hard drive. Here is a sample:

I need to idenitfy the ID number of the most recent duplicate. (If there is not duplicate, then the ID is the most recent). I tried using a formula like this:
=IF(IS(exact(B2:B3)),(if(exact(C2:C3),countif(D2:D3,D2)>D3,"Older"),"Newer"))
But can't seem to get the arguments right. Moreover, even if that did work, it would only compare the values immediately below.
A couple thoughts:
CAn I do a custom sort on the hash value, the Date, the time and then remove the duplicate hash values?
WOuldn't that keep the most recent in time?
If not, is there an easier way to find them?

I need to idenitfy the ID number of the most recent duplicate. (If there is not duplicate, then the ID is the most recent). I tried using a formula like this:
=IF(IS(exact(B2:B3)),(if(exact(C2:C3),countif(D2:D3,D2)>D3,"Older"),"Newer"))
But can't seem to get the arguments right. Moreover, even if that did work, it would only compare the values immediately below.
A couple thoughts:
CAn I do a custom sort on the hash value, the Date, the time and then remove the duplicate hash values?
WOuldn't that keep the most recent in time?
If not, is there an easier way to find them?
