    Question Any idea about .nva and .orb files?

    Hi All
    Recently I downloaded few books from internet in .nva and .orb formats. The same web site mentions about installing 'nva reader' and 'orb viewer' on windows.
    I would like to know whether these software are safe to install on Windows 8 computer or they are some sort of spyware or viruses.
    If so is there any other software to convert these books to .pdf format.
    Urgent help is needed.

    I subscribed to a paid medical website, most books are in PDF format. They tried to use some books in ORB file, after much protest from the users, they finally stop this format. Orb format are not supported by iOs. Now the new formats of ebooks are in NAV format, supported by iOs this time, we can't complain now as most users (sorry) were using iPads. The NAV app in apple store cost a whooping USD 15. Guess who develop this app, no price for getting it right, same owner as the med website!
    Generally the ORB and NAV should be safe, it's free for window users.

    And, this involves Windows 8 or 8.1.....HOW?

    This IS a Windows 8 forum, after all.

    A man with experience is never at the mercy of a man with an argument.
    Backup! Backup! Backup! Ghost rocks!

    Yeah, I am talking about the same format books.
    But are they safe for windows based computers, as rightly said, the same group of persons are involved in creating the software as are the book formats.
    Has anyone from Microsoft tested the authenticity of these formats.?

    I need help with NVA. I know how to convert ORB to PDF.

    Easy 30-step guide on converting .orb to .pdf.
    You will need:
    -One .orb file
    -One SWF Renderer
    -One Image2PDF
    -One Abby FineReader
    -One FoxitReader
    -One Adobe Reader XI

    1. Download ORB
    2. Change name of the file from ****.orb to ****.zip
    3. Unpack the file
    4. Shit + Right click the folder with the *.gau files
    5. Select 'open command line here"
    6. rename *.gau *.swf
    7. Select the last file.
    8. Shit + Home to select all files from the last to the first
    9. Right click the first file and select rename
    10. Rename it as (10000)
    11. Files are now numbered as (10000).swf, (10001).swf, (10002).swf, etc.
    12. Open SWF Renderer (I know, it is a paid software, but no other program does this)
    13. Set frame rate to 1, export format to PNG Encoder
    14. Click "Add to render queue SWF Files"
    15. Select all .swf files on folder (sometimes the program will crash if you select over 600 at a time).
    16. Click "start render"
    17. After finished, open Image2PDF
    18. Click "Add directory" or "Add files"
    19. Select the .png files created with SWF Renderer.
    20. Click "Make PDF"
    21. Open Abby FineReader
    22. Open the PDF you just created with Image2PDF
    23. After OCR, export it as PDF (not PDF/A)
    24. Now open FoxitReader
    25. Make your own Table of Contents for the PDF. Save it.
    26. Now open Adobe Reader XI
    27. Open the PDF you just created with Abby FineReader
    28. Click "Save As..." and save it. Do this because Adobe Reader XI makes PDF faster.
    29. ????
    30. PROFIT!!!!

    Thanks. But this process is too cumbersome.
    It looks very strange that two new persons register on windows forum only to reply to my post.
    Thanks anyway once again.

    If you are in doubt, just download the filetypes that you know.

    NVA Reader is a modified version of Sumatra PDF Reader. NVA files are PDF files that have been modified so they no longer work in normal PDF readers. For more information about the NVA format, including how to convert it back to PDF... do a search in the Sumatra forums.

    hi guys. A QUICK SOLUTION to all you mac users! don't pay to buy the nva reader on mac! just download the free windows program and install it ON YOUR MAC using WINE (wine bottler, an application that allows mac users to install or run windows based programs directly on mac)
    I used it and it works perfectly!
    ENJOY

    ps. this is the website for WINE : winebottler.kronenberg.org
    and its totally free for download
