# Reading MSDOS Disks on the QL – Part II: Copying MSDOS Files

Part I contained a brief description of the MSDOS disk organization. Table 1, below, expands on that description to include placement of clusters. The tabular form should allow visualization of interrelations among the disk parameters superior to any verbal description. For instance, the expressions in Procedure trsise should be fairly readily derivable from the Table. I have terminated the table with Track 2 because the patterns should be apparent by that time. “a and “b” indicate the first and second sectors of a pair, whether in a File Allocation Table (FAT) or a Cluster (Cl).
