Hello everybody!

I installed Windows Xp Embedded on a Compact Flash card. I have heard
about a compact flash file system: this is supposed to cache files
instead of reading and writing them continuously on the flash memory.
This should preserve flash memory lifetime..
Do you know where I can find and possibly download it?
Thank you much in advance.

It sounds like you're talking about the EWF - Enhanced Write Filter.
It's part of XPe you just need to make it part of your build.
 
Thank you much Adora Belle, that is exactly what I was looking for! I
added the component to my image, disabled previously used NT Loader and
now I am running the new image. Seems like I was not able to find any
reference to it in the documentation of Xp Embedded. Thank you! :-)

....we have documentation? When did that happen? Actually, being serious
for a mo, I'd suggest that you get hold of one of the XPe books - our
own Sean Liming wrote Windows XP Embedded Advanced, so anything in there
you need help with you're pretty likely to get help with here.
 
Thank you for your collaboration!
Should we consider switching to Xp Embedded I will get the book for
sure! :-)
Thank you, have a nice weekend!

Heidi, Thank you!

Mario, EWF and CF is a popular request. The XPe Supplemental Toolkit book
covers the latest solution. There is also a MSDN article and you can search
this news groups for more information.

I am back with a new question on EWF! :-)
Seems like I need applications that are aware of EWF if I want them to
use volatile memory instead of Compact Flash card... In other words, if
I have a one application designed to use a disk, it will keep on using
the Compact Flash regardless of EWF file system. Am I correct?

Thank you in advance!

Applications don't have to be modified. The EWF protected partition will
still look like a read-writable disk. It is jsut the implementation of the
EWF Disk overylay vs. RAM (or RAM-REG) overlay. With Disk overlay all data
is preserved. with ram, the data is lost on reboot.

Thank you once again Sean. I understand that I don't have to modify my
applications, but I am sorry I don't get the EWF vs. RAM overlay
issue... Would you be so kind to describe me what it is? Thankx!
