In a storage medium, an address space is defined which is divided into a first area and a second area. According to the invention, at least one file is stored on the medium which is split into small data packets and large data packets. All small data packets are stored on said first area, and all large data packets are stored on said second area. A single file allocation table (FAT) is used and is small by having one entry per data packet.

The invention relates to a double-recording file quality inspection method and device, computer equipment, a storage medium and a computer program product. The double-recording file quality inspection method can be applied to the financial field or other fields. The method comprises the following steps: acquiring video recording information and sound recording information in a double-recording file for a first business object and a second business object; extracting a target facial feature from a video frame corresponding to the video recording information; the target facial features comprise a first facial feature corresponding to the first business object and a second facial feature corresponding to the second business object; comparing the target facial feature with a pre-acquired reference facial feature, and acquiring first quality inspection information corresponding to the video information based on a comparison result; the second quality inspection information corresponding to the recording information is acquired, and the quality inspection result corresponding to the double-recording file is determined based on the first quality inspection information and the second quality inspection information, so that manual quality inspection of the double-recording file can be avoided, and the quality inspection efficiency and the quality inspection quality are effectively considered.
