    Indexing Options internals


    Dear friends hallo,

    One day I noticed that the processes responsible for indexing were taking up too much process power. I noticed that this happened because I transferred my e-book collection to my PC. Windows was trying to index the contents of these massive pdf files. At the same time I realized that I had never tried to search the contents of a file. So I went through every file type and I changed its filter description to "File Properties Only".

    If you go through this list, you will realize it is very big so the whole process took a long time to be completed. One day, after a Windows Update, the Indexing Options were reset (?). So I had to go through all this hassle again. If anyone knows the internals of Windows on this subject, I have the following questions:

    -Which is the file that windows stores its indexing options? Can it be backed up and restored after the aforementioned incident? Is there any tool that I can use while Windows saves changes to this file, to locate the file in order to be able to answer questions like that in different situations?

    -Is it possible to change the filter description of all file types alltogether and not one by one?

    -Is there any documentation regarding the data format of these kind of files? In particular, is there a standard way that Windows store key-value pairs so a Windows API can be used to read/write the contents of such files?

    I understand that my questions dive much deeper than the mere resolution of my original problem. I just find that as an opportunity to learn. Thanks!

    Hi, suggest you see Indexing Options in the Control Panel
    (Windows key + X, click Control Panel)

    Please explore the options and post back any remaining queries.

    Note:
    1. Users (sthg there) must be indexed to support search in Settings.
    2. Cortana 'My Stuff' search seems to be indexed items only

    Yes, I know these options. If you click at File Types you get a list of known file extensions where you can choose if you want file content indexing for every file type. My basic question is how can i avoid getting to each file type separately and changing the value of the desired property or, if I do it once, how can I back up the file Windows is using to save these changes.

    I think the indexing options for file associations are stored (e.g.) here:
    HKU\S-1-5-21-2598030854-2856894942-2756517887-1001\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\UserAssist\{CEBFF5CD-ACE2-4F4F-9178-9926F41749EA}\Count\HRZR_PGYFRFFVBA:

    That's what appears to be what's significantly changed when changing one of those settings.

    Is your question:
    I want to change the settings for file extensions in Advanced Settings, File Types, all at once, rather than each individually. Is there a way to do this?

    Yes Sir! That is the basic question. Or at least that was my initial concern!
