USB Duplicator - Operations - Brief Copy

Brief Copy performs actions only the sectors that contain data and skips any blank sectors (including information hidden in sub channels). This mode is commonly the fastest mode and it supports the following file systems: FAT16, FAT32, exFAT NTFS, EXT2, EXT3, EXT4, HFSX, and HFS+.

Note: If the Source is not formatted as a supported file system, then the duplicator will automatically switch to Full Copy.
