How to Add or Remove a File Type from the Index in Windows 7 and Windows 8
The Index keeps track of the files on your computer and stores information about the files, including the file name, date modified, and properties like author, tags, and rating. The index is used to make searching for files in Windows much faster. Instead of looking through your entire hard disk for a file name or file property, Windows scans the index, which allows most results to appear in a small fraction of the time that a search without the index would take.
This will show you how to add or remove a file extension type from the index, for the included folder locations, to be included or not in the search results in Windows 7 and Windows 8.
When you add a file type, you have the option to have the file indexed by one of the options below.
Index Properties Only - The metadata for that file will be included in the index. For example, file name, date modified, author, etc... It will basically be what you see when you right click on the file and click on Properties and the Details tab.
Index Properties and File Contents - The above will be inlcuded as well as the contents of the file itself if available. For example, all text in a Notepad .txt file. Not all file types contain text though.
1. Open the Control Panel (icons view) in Windows 7 or Windows 8, and click/tap on Indexing Options icon.
2. Click/tap on the Advanced button. (See screenshot below)
3. If prompted by UAC, then click/tap on Yes.
4. Click/tap on the File Types tab. (See screenshot below)
5. To Add a File Type to the Index
A) Select and check the box for the listed file extension that you want to add. (See screenshot above)
If the file extension is not listed, then in the Add new extension to list box, type in the file name extension (ex: txt) and click on the Add button.
B) Select (dot) if you want this file to be indexed using Index Properties Only or Index Properties and File Contents. (See screenshot below step 4) NOTE:See the note box at the top of the tutorial for more on this.
C) Go to step 7.
6. To Remove a File Type from the Index
A) Select and uncheck the box for the listed file extension that you want to remove. (See screenshot below step 4)
7. Repeat steps 5 and 6 if you want to add or remove anymore file extention types.
8. When finished, click/tap on OK. (See screenshot below step 4)
9. Click/tap on OK. (See screenshot below)
10. After a moment, you will notice the index being rebuilt. Click/tap on Close. (See screenshot below step 2)
Could you advise if there is a way of removing an extension that you have added from the list of file types entirely?
I wanted to add the file type 'LIB' but inadvertently added 'lib'. The searches appear to be case sensitive as regards file extensions, so my *.LIB files are not included in searches. However, I can't add the 'LIB' extension to the list of file types as 'lib' is now in the list.
I seem to have snookered myself! Is there a way around this? I can't see a restore defaults option.
Yes, the folder is included in the index locations.
If I rename the files from *.LIB to *.lib then the contents of the files are searched and I can locate the pattern that I am searching for. If I don't make the name change then the search always returns nothing.
So, I have a work around in that I can rename the files before and after I run a search, but obviously this is a bit of a pain.
In the explanation of how to do this in the forum, it says to click add file type at the bottom of the list.
It has a screen shot of the list and the button, below the list
Unfortunately on my computer there is no add file type button visible.
As requested, screen shots re the set associations list. As I mentioned in my last post, there is no add file type button at the bottom of the list. We want to add the .sch extension and link it with schematics, but there is no buttons or other method visible, above or below the list, for adding an extension which is isn't already there.
As requested, I have attached views of the set associations list. As I mentioned in my last post, there are no buttons to add extensions visible above or below the list. We want to add .sch for use by schematics.
