Looking at Yii https://www.yiiframework.com/wiki/148/understanding-assets#maintenance-of-the-assets-folder , it's clear we can delete content inside asset directiry, but unclear if it was cleaned automatically .

I don't find any related code in CAssetManager , adding a rmdir is easy, but if Yii have a delete system : it's not needed.

Do you find something related ?

We don't need to delete old assets?

? I think we need to delete it big size finally if we don't delete it.

BUT : when i look at my asset folder : i only have the last 3 days old asset folder, then maybe Yii have own system somewhere

Looking again today : yesterday have saturday directory, today : no saturday directory.

I close it but if someone else find where it's deleted , i'm happpy to know.

Even the wisest cannot know.
