Is FBWF related with Virtual Memory RRS feed

  • Question

  • There is an option named "Disable page-file support" in File Based Write Filter settings.It is checked by default.

    My question is:Is FBWF confilicted with Virtual Memory?Does it mean that if I enable FBWF then I mustn't set Virtual Memory size?(My Computer-Properties-Performance-Settings-Advanced-Virtual Memory-size)

  • FBWF EWF caches disk writes in RAM (which is limited). Writes to page file (if present) will consume RAM since these disk writes get redirected by FBWF EWF. This defeats the purpose of having the page file ! So page files are not recommended when using write filters.

  • Thank you for your reply. In fact I used to set Virtural Memory size when FBWF is enabled in XPE,it seemed all right. :) Another question is if i use FBWF in WES7,can I check the "Automatically manage paging file size for all drivers" checkbox?

  • Yes, you are right , my comments above apply only to EWF not FBWF. Sorry for the confusion. I updated the post above.
