这是我的文件夹和文件：
/root/first/file1.mkv
/root/second/file2.mkv
/root/second/another3.mkv
/root/third/into/file4.mkv
/root/third/file5.mkv
/root/four/file6.mkv
我想使用htaccess并将其全部更改为：
?file=download/first/file1.mkv
?file=download/second/file2.mkv
?file=download/second/another3.mkv
?file=download/third/into/file4.mkv
?file=download/third/file5.mkv
?file=download/four/file6.mkv
如何针对此问题在根文件夹中写入htaccess？
