那么怎么添加自己想要的文件类型呢？
插件法：安装 WP Add Mime Types，设置 - MIME TYPE SETTINGS
点击 reference 去找到标准的写法，贴过来保存即可。
代码法：其实更简单，请自行搜索。
另外
- 如果是添加字体，直接上传并非首选，很多编辑器里面可以配置，比如elementor和wpbakery都是支持的。
- 通过woocommerce上传产品的时候，如果提示不支持csv，那基本上是因为csv格式有问题，要另存为新的csv文件，因为默认保存的是Unicode编码方式，尝试一下 utf8吧，不明觉厉。
- 如果编码改了，仍然无法导入，就用ftp先上传吧。如果ftp还不行，那你传错服务器了。
