Hi Alan,

On 2020-04-22 20:22:56, you wrote to all:

I get about the same weird result as August:

Would you like to replace the existing file:
  Path:     .\NODELIST.108
  Size:     165590 bytes (162 KiB)
  Modified: 2020-04-17 00:25:02
with the file from archive:
  Path:     NODELIST.108

But afterwards there is a correct unpacked NODELIST.108 file.

When I rename the NODELIST.Z08 to NODELIST.ZIP, it unpacks without complaining:

Everything is Ok

So it seems 7z gets confused by the .Z08 extension. It probably thinks it's file 8 in a multiple file archive...


Bye, Wilfred.
