Thanks for the quick reply!
The last data restore would have occurred on in January. Our last digit doesn't correspond with an I or R as in your example, but D and H. Our currently opened batches are:
ARA0008D.CNA (actual batch)
ARA0008H.CNA
ARA0009D.CNA (actual batch)
ARA0009H.CNA
ARA0010D.CNA (actual batch)
ARA0010H.CNA
ARA0011D.CNA (skipped batch)
ARA0011H.CNA
ARA0012D.CNA (skipped batch)
ARA0012H.CNA
ARA0013D.CNA (actual batch)
ARA0013H.CNA

So we should delete the 4 batch files for 11 and 12? Would they eventually clear on their own?
Thanks
