Updating files of a protected CF

[Guest]

Hi all,

I have a CF protected by EWF(RAM).
And my system is updating a fixed number of files continuously.
For example, 64 files will be updated continuously.

In this case, the memory consumption by EWF will be
increasing for every update?

Thanks in advance.

Yes, if the files continue to increase in size.

The alternative is to use the new File Based Write Filter that is coming in
FP2007. FBWF allows the files you select to be written through to the disk.

If flash life is a concern so you may want to off load to a different disk
or drive.

Thanks Sean!

Yes, if the files continue to increase in size.

So, there's no problem if file sizes don't change, isn't it?

Carlos,

Thanks Sean!

If the file size doesn't change the EWF overlay usage won't increase unless you move the file location on the disk.

Basically, since EWF is disk level filter, the rule is that the disk (partition) blocks occupied by the file should not change if
you want the overlay size not to increase if you change the file content.
