Title: Read ahead caching (turn off?)
Post by: Andy K on February 15, 2009, 12:07

:bawl:

When you select a group of files in explorer in vista (and XP I think) it automatically starts trying to read them into cache just incase you want to copy them.

This is just about ok if they are local small files, but I really p***ing me off now, as I am trying to copy 500GB from a CDRW (which doesn't seam to be very fast).

As soon as I even select them it's processing away and eventually crashes.

Would love to turn this feature off (although may not fix this problem)
can you ? any idea's how ?

Thanks.

P.S - I am so feed up with Windows that I should consider an alternative O/S

Afaik, Andy, there's no caching setting for an optical drive, only HDs.

In which case, you might want to read this (http://www.pc-pals.com/smf/index.php?topic=27620.0;topicseen), Andy.

Sorry, I can't help with the caching thing either, but I trust what Rik says.  :)

No caching per se.  However if any of them are archive (.zip etc) files then windows explorer will try to discover the directory contents for them; which, if they are large, may take a long time.  It is possible to unregister the dll that handles this if you wish using regsvr32:

Code: [Select]

regsvr32 /u C:\Windows\System32\zipfldr.dll

I managed to do the job, by using a USB stick. Why I didn't use this in the first place I don't know  :)x

The files were driver files.

I take a look at the link thanks
