WB & DirectoryOpus indicate that an amigados disk formated with FFS has 899072 bytes free. When I try to copy files from a directory on my harddisk that DirectoryOpus tells me contains 809564 bytes of files, DirectoryOpus tells me that the disk is full before all the files are copied over. Are there some 'hidden' bytes used that cause the discrepency? =Rick=

Hi Richard. When DOpus displayes the byte count in the status bar (and when you use the GetSizes/Byte command), it just displays a total of the lengths of each file. However, each file can use up to two additional blocks (it always uses one additional block) for storing header information, etc. FFS data blocks are 512 bytes each, so you can see that for each file you might need up to 1024 bytes extra to fit it on the disk. The new CheckFit command in Opus 4.0 takes this "blocking-factor" into account, and displays a true representation of how much space you will require on the floppy. Jon
