Program to archive a directory tree as a number of archives which do not exceed a given size. See Escape from RISC OS to discover why this is useful.
The archives are named:
Volume000/zip
Volume001/zip
...
The main thing is to get the direction setting right - do you want to go from directory tree to archives, or archives to directory tree. Typically you use the first option and then the second.
In both cases, usually the destination folder should be empty.
The program uses SparkFS as its way of interacting with Zip files. If you're dealing with a lot of files, SparkFS has to be configured with a large max memory slot in its choices.
I set up SparkFS to not compress data in Zips - faster, more certain to be accurate, less to go wrong.
SparkFS cannot write Zip files longer than 2GB, as a result the value for the max size in MB should not be bigger than 2000MB, a prudent limit is 1000MB. I used 500MB.
