KiCad Project Manager doesn't show all files

The Project Manager/File Browser doesn’t show all files in the directory for the project.

For example I’ve added two files relating to the necessary ROM image (Earthy_Rom.txt and Earthy_Rom.bin) but only the .txt file is shown. Similarly I added an Excel (.xls) file derived from the BOM .csv file. These simply aren’t shown, and I think they should be.

Am I missing a setting that will show all files in the project directory?

Thanks, David

The files KiCad shows or hides are an arbitrary mystery to me.
I make project documentation in asciidoc format (extension .adoc) and KiCad also does not show those.

And the same for the “Archive Project” utility. Because I can’t remember or adjust what it does (not) backup, it’s useless to me. I once made an (informal) remark about some way to store in the project which filetypes should be included or excluded from the view (and archive) but at that time there was no enthusiasm for it.

It seems fair for the project manager not to show some of the contents of the project directory. If KiCad does not have its own tool to display or process them, I’m ok with certain file types not being shown.
Sometimes, for example, I’ll have a bitmap image of a pcb that I’m going to include in documentation.

I just click on the icon to open a File Explorer to see all the files if I need to (indicated mid-left of screenshot above).

KiCad’s Project Manager only shows files it recognizes (schematics, PCBs, libs). .bin and .xls won’t appear. Best practice: keep them in subfolders and reference externally.

Meh. In the screenshot from TimC_Harris, it shows an README.md (Markdown), while for me it does not show *.adoc (AsciiDoc) and that is pure discrimination!

I know - that’s what I am complaining about.
