To get started, follow these steps:
  1. Download and run setup for your machine (32-bit or 64-bit)
  2. Open the File Association Manager (under the File Metadata entry in the Start menu, if you still have one)
  3. Scroll down to and select the extension or extensions of your choice from amongst those that currently have no handler (.txt is a good starting point) and click Add File Meta Handler
  4. Open an Explorer window and select a file of the chosen type. Metadata edit entries should appear in the Preview Panel at the bottom of the window.
  5. If nothing shows up, try logging off and on, or equivalently, killing all instances of explorer.exe and restarting it. Sometimes it doesn't catch on to its new powers immediately.
  6. If all is well, great! But If you're having trouble, check the FAQ, and search previous Discussions. And if that still doesn't get you going, open a new Discussion and we'll try to help.
Or, if you don't like all those dire download warnings (and I don't), grab the source, read, build and then goto step 1. How did we ever trust anything before FOSS?

I will close with a handy tip for Windows 8 and Windows 10 users. Because Explorer remembers the settings for an extension when it reads them, it is sometimes necessary to restart Explorer after having made changes using the File Association Manager. In Windows 8 and 10, Task Manager makes this really easy. If you select Windows Explorer in the list of running Apps, the button at the lower right will restart all instances of Explorer at a stroke:

I've tested File Metadata on Win8.1 64-bit and it works!
And a feature still needed.
My main file manager is TC(Total Commander).
I can NOT see the file's metadata which I've edited and saved in Windows Explorer.
Also, when I right click, choose properties and go to Details tab, the metadata appears there can NOT be edited.
Please help to add this feature that enables metadata editing in TC.

In Win 8/8.1 the fields are shown in the Details pane in explorer, where they can be edited (Click on the text to the right of a heading).
The Details context menu property sheet is replaced by one with similar headings and fields to those in the Details pane. Note you have to click several characters to the right of a heading to see the editable field.

Sorry guys, I missed these. I only get notified of new issues and discussions. If you're still out there and need help, please open a discussion.

I followed steps 1 through 4 in your example above (using "txt" as a model) but see no way I can edit the COMMENT field of my 'txt' files in Explorer. Can you replace STEP 5 with a description of how to do this?

The properties are shown at the bottom of the explorer page, but after I type a new value in a field, like Title, when I select save, I get an error message:
Error 0x800700C1: MyFileName is not a valid Win32 application.
I am running 64 bit Windows 7 and the file is a pdf.
