You can use 7-zip to unzip your BRIS DRF files, or most other compressed files. This will let you unzip ALL of the files you download at one time. What I do is create a folder with the race date, then copy all of the BRIS DRF files into that folder. You can open 7-zip and navigate to that folder. Highlight all of the files, then click on
Extract. This saves a lot of time from having to unzip them one at a time.
