MS-DOS 6.22 RESTORE attribute persistence across differing FAT disk formats

The BACKUP and RESTORE utilities in MS-DOS 6.22 are used to archive file data and directory structures into sequential .BAK files. While these tools maintain standard file metadata, behavior varies when restoring archives to disks with different FAT sizes (such as transitioning from 16-bit to 32-bit FAT).

There is uncertainty regarding how the RESTORE command handles hidden or system attributes when the target disk format differs from the source disk used during the backup process. Specifically, it is unclear if these attributes are consistently preserved or if the restoration process defaults to standard file attributes during the directory recreation phase.

• Does the RESTORE command preserve hidden and system attributes when moving data between different FAT versions?
• What is the expected behavior for attribute mapping when the target disk's file system constraints differ from the source?
