Delete a specific missing shx file?

[StevenB]

I'm going through our library of LISP files and cleaning out old unused files. There was an old LISP routine that was loading in a shape shx file automatically into any drawing opened.

I need to make a simple LISP routine to delete just a specific shx file reference. From searching I've only seen a couple that purge all unreferenced shx files, this won't work because we'd still need to know if CAD received from clients are missing required shx files.

I'd leave AutoCAD's LTYPESHP.SHX in there, there are others required for verticals like Civil 3D.
What's the name of the shape file?
A simple macro: "-PURGE SHape " followed by the shape name should do it.

Hello Tom.

I politely ask you to be more specific. Do you want to Purge a Shape file but you are not able to identify the file name, or what?

Something like this?

(vl-cmdf "._purge" "_SH" "ShapeFile" "_N")

Oddly... this doesn't seem to work when you specify a certain shape file, with or without the [.shx].
Feels like a bug.


Anyone else try this?

I even tried "-PURGE SH ShapeFile N" at the command line in Civil 3d 2017 and was told "No unreferenced shape files found." Same shape file is removed easily using the dialog box version. Bug?
