For the ASN.1 GenBank release files, the total number of files decreased substantially from 2,771 to 1,199. This is because the maximum size of an ASN.1 file was increased to as much as 700MB (compressed), due to a change in how we process the ASN.1 version of release data.
For downloading purposes, please keep in mind that the uncompressed GenBank release 254.0 sequence data flat files require roughly 3,052 GB. The ASN.1 data files require approximately 1,509 GB.
