# 保存滤件

保存新建立的滤件或者修改的滤件，可在菜单 File 中的 Save 或者 Save As

如果修改 EndNote 默认安装夹 Filters 子文件夹下的已有的滤件，必须使用 Save As 命令保存在人个滤件夹下，这样不会覆盖原有的滤件。如果修改是个人文件夹下的滤件，可以使用保存命令，或者使用保存为命令建立一个滤件备份。EndNote 的默认文件夹详见[EndNote默认文件夹](https://app.gitbook.com/s/-LrgCHEEK5wsSALfCziF/filters/18Prefs/Folder_Locations.htm)

EndNote自动保存新滤件在个人文件夹内，但是有时可能需要选择不同的文件夹。文件夹可见[EndNote 默认文件夹](https://app.gitbook.com/s/-LrgCHEEK5wsSALfCziF/filters/18Prefs/Folder_Locations.htm)

EndNote滤件的扩展名是 .ENF，如 HowSci.enf
