使用roxy fieman一次选择和删除多个文件

I am using roxy fileman with ckeditor in one of my websites. I find it weird that there is no possibility to select multiple files and delete them all at once.

It's really annoying when you have lots of files in a directory and you find yourself forced to delete them one by one.

Did I miss something? Is it doable and I just don't know how to do it? Thanks in advance

No, it's not build in. Though you could write your own function, you would have to write a part to select multiple files (take a look at the functions setFile() and getSelectedFile()) and could run a loop to delete the files at once (take a look at the deleteFile() function).
