My <http://www.merlyn.demon.co.uk/linxchek.htm> is undoubtedly a Web
page.  A browser automatically makes a local copy, and displays it; and
that thus-displayed page cannot read the local filesystem.  But, with
menu File, Save [Page] As, one gets a local copy which the browser can
read and display; and that can then read the local filesystem.

Try it yourself - that might at least help to debug the instructions.

H'mmm - can a cached copy be found and read as a file, independently of
its cachedness, and what does it then do if asked to read the local
filesystem?


My <http://www.merlyn.demon.co.uk/programs/32-bit/seek.hta> is
presumably a Web page.  Firefox will fetch it and display it in "View
Source" manner.  But MS IE 8 can fetch it and display it in an HTML GUI
manner.  Press the SEEK button and it will read the local disc and
display information from it, with a short delay.  Usually, use WIPE
between SEEKs.  The "input type=text" element needs a folder reference,
not a file one.  Y is short for "Yesterday".

That is freshly tested on the PC on which it was written.  It might be
necessary for others to import and emplace my seakfyle.js; I cannot tell
from here.

And if you use the link "Instructions", you may find it useful (in which
case please take and use a true local copy (of both)).

The wordings are generally obscure or capable of misinterpretation.
Especially the word "I".
