I’ve eMailed the author regarding this.

yes, but, have you got the latest version of the zip module:

from back at the start of August 2015 – see my mail list (archive).

Yes I’ve fallen by the wayside, I was supposed to being doing a complete new SparkFS version. I get involved in other things. Every week I try to do some RISC OS software.

… and the author has replied 8-)

Thanks for the link, it does indeed resolve the issue.
