OFAC recently modernized the software that the office uses to generate its SDALL.ZIP and SDN_XML.ZIP files. As a result of this modernization, the nomenclature of the files contained in SDALL.ZIP and SDN_XML.ZIP have changed. Previously all files contained in this zip file had a name that was in all uppercase characters. OFAC's new software is compressing these same files into the SDALL.ZIP and SDN_XML.ZIP files using file names that are in all lowercase characters. While OFAC has no plans to change the file names in SDALL.ZIP and SDN_XML.ZIP back to full uppercase characters, the office does recommend that users with automated download/decompression scripts in place modify these scripts to avoid case sensitivity.
