Code Editor not listing files/folders in the right order

[superpoincare]

On new installations on test sites, I have seen the correct order for listing of files/folders in the code editor.

ie:

• important files
• folders
• files in the root.

However, in my installation, I don't get the same order.

Example screenshot attached.

readme.txt and composer.json should be lower in the list.

Thanks for the report!

Looking at get_plugin_files()​ used to display the tree, the default order is:

• The main plugin file.
• The rest of the files, in alphabetical order.

This appears to match what I'm seeing on a clean install:

query-monitor.php
assets 
classes 
collectors 
composer.json 
dispatchers 
output 
readme.txt 
wp-content 

Does the issue still happen with all plugins disabled and a default theme activated?

#24049 is a related ticket, but I can't reproduce that one either in current trunk, appears to be fixed in [41806].

I am getting

query-monitor.php
assets (folder)
classes (folder)
collectors (folder)
dispatchers (folder)
output (folder)
wp-content (folder)
composer.json
readme.txt

on the Sandbox test site on a clean install.

Which seems different from yours but seems most natural but different from yours.

On my personal site, I used the health check plugin and entered the troubleshoot mode, but still am getting the same result as the screenshot.

Looking at this again with Theme Editor and Twenty Nineteen on Windows, the order is indeed a bit random, apparently a mix of sorting by extension and name:

style.css
functions.php
print.css
style-editor-customizer.css
style-editor.css
style-rtl.css
js (folder)
postcss.config.js
package-lock.json
package.json
404.php
archive.php
classes (folder)
comments.php
footer.php
header.php
image.php
inc (folder)
index.php
page.php
search.php
single.php
template-parts (folder)
print.scss
sass (folder)
style-editor-customizer.scss
style-editor.scss
style.scss
readme.txt

style.css and functions.php are at the top, as expected​, but the rest of the list could indeed be sorted in a more logical order.
