I wrote it a long time ago as part of the Embedded Boot Loader (EBL). The EBL was a proof of concept I wrote in something like 2007 to show an EFI system could have a smaller footprint like uBoot. The EFIFileLib uses the device name (volume name) scheme of the EBL This scheme was unique to the EBL. For example the fs3: volume name in the EFIFileLib is not the same as the volume names in the UEFI Shell. </div><div><br class=""></div><div>The EBL is obsolete and got replaced by the UEFI Shell. I think EFIFileLib ended up getting used in other places so it stayed around longer. </div><div><table class="js-file-line-container highlight tab-size" data-tab-size="8" data-paste-markdown-skip="" style="box-sizing: border-box;
