KCFinder Plugin for GetSimple 3.x

[Sergey12]

Does anyone know how to get this to hide file types (ie. .htaccess, index.php, etc.) so that users dont delete these?

Also interested in this question.
I know that a lot of time has passed, but I hope it is still relevant.
I found a modified version of the KCFinder plugin (the old version 1.2, it seems, was in some kind of assembly).
In this version, the .htaccess file is not displayed.
I tried to figure out and transfer part of the code to the new version, but it didn’t work out - I don’t really understand php.
Perhaps you can find the part of the code responsible for displaying and filtering files and share information here. Archive uploaded here: https://dropmefiles.com/JKDA0
It is also very interesting how you can add the ability to create image thumbnails on the principle of a standard getsimple loader.
I am sorry for my English.
