Reset and reloading all books on Sony PRS-350 so the status on books is not "New".
After you have reloaded books on reader.(I used Calibre.)
(Example below is for EPUB format but works any format read by Sony Reader LRF Pdf etc) for LRF would be .LRF"> and Pdf would be .Pdf"> etc)
Open via windows File Path folder by clicking on Start/Computer/READER/database/cache.
You will see three files named:- 1 cacheExt.XML 2 cacheExtSchema_1.5.xsb 3 media.XML.
Open with Wordpad file named
cacheExt.XML
Then open by clicking on right hand top second button "REPLACE" button.
Then enter the letters in the Find what:
.epub" >
Then enter the letters in the Replace with:
.epub" opened="true">
(Remember spacing etc needs to be just right)
Then click button "Replace" (and see if it has replaced .epub"> with .epub" opened="true">)
If it has and you have lots of books just click button "Replace All".
Then unplug USB lead wait for reader to sync itself and there should be no "New" books.
