Use a database where you store the file names (for example using a kind
of maintance script which regularly scans the directory and updates a
database table with the current list of files). Otherwise you would have
to scan the directory with every request to get the existing file names
as a list and find out, which one matches - and this would not be very
efficient.

Nope.

WordPress for example does this "auto completion" as well - but the URLs
in WordPress are already only in the database and don't even exist as
files. Many other CMSes handle this in a similar way.

So for example:

When you access

<http://arnowelzel.de/wp/en/tools/spoke>

you will get redirected to the real URL

<http://arnowelzel.de/wp/en/tools/spoke-length-calculator>

But this is not done to provide and kind of SEO - it's just for
convenience. The opposite is true: Using descriptive URLs is better
since the URLs are then also part of the search.

Also see:

<https://moz.com/blog/15-seo-best-practices-for-structuring-urls>

What really hits search engine results is changing old URLs without
forwarding to the new ones.

<http://www.w3.org/Provider/Style/URI.html> is still true.
