Preview LSP files in Windows Explorer

[cadpoobah]

Just passing this along, fwiw.

I inherited a folder full of AutoLISP files from previous CAD Manager, and needed a way to peruse them. The "preview pane" in Windows Explorer didn't recognize LSP files as a text file. I ran across this registry hack for .LOG files that, with a slight tweak, worked like a charm.

I followed Ivan's instructions for creating a REG file and just modified it, changing the ".log" to ".lsp". It creates a text (REG) file that modifies your registry accordingly.

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.lsp]
@="txtfile"
"Content Type"="text/plain"
"PerceivedType"="text"

Obviously, you can tweak this to work with other types of code files as well.

Enjoy!

Hi Chris

I am trying to get the preview to work and tried copying your code and making a .reg file but that did not work. I also tried typing the settings in manually,but think they are wrong. Maybe as a Windows 10 machine. Can you advise what the manual settings should be. I have made them all just string entries is the @ symbolled one meant to be something else?



Regards

Justin

The OP's original .REG code works just fine for me on Win10x64 Enterprise, FWIW:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.lsp]
@="txtfile"
"Content Type"="text/plain"
"PerceivedType"="text"

As to your question, @ in a .REG file simply means '(Default)'.

Cheers
