microsoft office 2007
 

i got a worker who does a lot of record in excel...she was recently updated
to 2007 office professional...on some records when she opens it up from a
..xls format she converts is to xlsx format but now she has 2 copies...one in
the old format and the one in the new...in other folders she does the exact
same thing and it converts it but does not leave a copy of the old...is there
anything special she needs to do on the ones that is leaving the copies of
the old format in the folder as well as the converted copy?
