When you click a file with the preview window open, windows will show you a preview if windows knows how to do it. But files like .json and .py will not preview.
It would be sometimes useful in the open dialog of any editor to preview a script before opening it. Most open dialogs will inherit the windows explorer preview settings but ….
How do you make windows associate .py files as text like files for the preview pane?
You need a Preview Handler for ZIP files, and 7-Zip doesn't provide one. I don't know of any such handler except the one available via the View Data Your Way With Our Managed Preview Handler Framework article on MSDN.
Try it out; it was written for Vista (and Outlook 2007) but should work equally well on Windows 7:
The code download for this article includes a framework that makes it a snap to implement your own preview handlers, and it provides several sample previewers (including previewers for PDF, XML, ZIP, MSI, BIN, CSV, XPS, and XAML files).
Start >> Regedit.exe
Find HKEY_CLASSES_ROOT\.m3u key and check the 'Default' setting (in my case VLC.m3u)
Find HKEY_CLASSES_ROOT\VLC.m3u (in this path substitute VLC.m3u with the value of your default setting in HKEY_CLASSES_ROOT\.m3u)
Create a new key in HKEY_CLASSES_ROOT\VLC.m3u: shellex
Then in HKEY_CLASSES_ROOT\VLC.m3u\shellex also a new key: {8895b1c6-b41f-4c1c-a562-0d564250836f}, so it should look like this:
The {8895b1c6-b41f-4c1c-a562-0d564250836f} key tells Windows that you want to use a preview handler, now you only should specify which one you want to use.
Set HKEY_CLASSES_ROOT\VLC.m3u\{8895b1c6-b41f-4c1c-a562-0d564250836f} Default to this value: {1531d583-8375-4d3f-b5fb-d23bbd169f22} (text handler ID)
If you want to use other handlers in shell you can find their ID's in the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\PreviewHandlers

The answer came from this link this link as music2myear mentioned but the accepted answer in that link did not work for me.
What worked for me was 2nd answer in the thread. Member user255627 points out the correct key is
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.pywhich requires attributePerceivedType REG_SZ text.I created an attribute in this key with
regcommand. You can substitute .py with any extension type and enable a bunch of extensions this way. No need for a external program as mentioned in other thread.You can query like this.
Thanks for the help guys. very useful.
