Thanks but the Forum is playing silly buggers.
When i search for "NT File Scripting" i am informed that the word NT is too small, the minimum length of a word is 3 characters.
Well - that progress.
I will try again on "Shell scripting".
Anyway, many thanks for the advice.
I grew up on computers from the dark ages - Elliot 803s (the size of a house and with a whopping 8K memory and best used as a room heater), Commodore Pets (IEEE, a tape drive and later a disk drive) etc etc and I used to have about 200 books on computing and computer languages (from machine code to Algol to html to ....). Now I am retired I rarely use anything other than Windows so I have very few books.
