There are some .ARC files that XTree cannot recognise. To handle these a utility program, ARC2ZIP, is provided which converts .ARC files to the .ZIP format. I recommend that you use this on all your .ARC files, for the .ZIP equivalents are usually much more compact.
By their very nature, archives can be very large. How do you cope with getting a large archive file - larger that the capacity of a floppy disk - onto floppies? There are two ways.
If the files have not yet been compressed and are on your hard disk, just adopt the normal XTree procedure for creating an archive. Tag all the files to be archived, select S (Showall) if they span more than one directory, and key Ctrl-F5. Include the drive letter of your floppy drive in the archive file name. XTree will compress the files to a .ZIP file on the floppy disk, and when this is full you will be prompted to insert another disk. You will end up with a set of floppy disks each containing a complete free-standing .ZIP file, all with the same name. To find which file is contained in an archive file, just View it; there is no need to log the archive with Alt-F5.
If you already have a large .ZIP file, use ARC2ZIP to copy this on to a series of floppies.
