Hi all, I'm trying to get the Windows 7 Search index to include files with no extension. I want them to be treated the same as txt files. For example, I've created two text files in the same folder of the C drive, each containing the single word "Brandshop". The first file is called "test" (with no extension) and the second file is called "test.txt". When I search for Brandshop from the Start menu, I only get "test.txt" back, I don't get "test". Searching for the name "test" works; it returns both files. The problem is that the contents of the file "test" are not being indexed. I checked the properties of both files and they are both set to allow indexing. Both files are in the same folder so it is not a folder issue. I've tried adding a new file type to Indexing Options -> Advanced -> File Types. I went to "Add extension to list" and typed a single space. This seems to create a file type with a blank extension. I set it to "Index Properties and File Contents" and it is listed as using "Plain Text Filter". But it doesn't fix the problem. Note this single-space extension trick did previously work in Windows Vista, but not Windows 7. I am using Windows 7 Enterprise 64-bit. Thanks for any assistance.

Hi,According my search, it seems that this is by design.

You mean it is by design that the user can add a file type with blank extension but the indexer silently won't index it? And that this feature that worked under Vista would silently not work under Windows 7?

Yes, this can be an update in windows 7 as the "Space" is too typical to represent an extension name when writting into registry.In addition, a workaround option, the third party software http://www.ghisler.com/ can achieve this function. It works fine in my machine.
