I understand, but you update it from time to time, did you not have an Script?, that replace automatical this clan_icons folder.
As example, you set the Checkpoint in the installer for EU clan Icons, or NA or ASIA and so on, and a script, check & download the package from https://wows.mv-smirnov.org/images/zip.php?realm=eu and replace it. just this
At least not you will replace it, then the a program will replace it, download the package and extract them.
Job done and both sides have an win win.
kind regards
