Hi,

I am working on a site with lots of front-end file uploads, and have hit some difficulties with filenames causing issues in the panel. For example, if a user uploads this file:

`blank & something {{} [].pdf`

It gets saved to the content folder as:

`blank &amp; something {{} [].pdf`

Then when the client clicks on this in the Kirby panel there is the error message “ **The view could not be found** ”

I am now trying to use `Str::slug` to fix this (there may be a better way), so I can convert the filename to something better. However, when I do this it is also applying to the extension, so the file now looks like:

`blank-amp-something-pdf`

Which is no good.

What is the best way of sanitizing the filenames, while keeping the extension? Is it possible to get `Str::slug` to ignore ‘.’ characters?

Any help gratefully appreciated!
