# 打开

EndNote 程序已打开时，打开数据库可以从菜单 File >> Open Librar。如果之前曾打开过数据库，可以从数据库列表中选择需要打开的数据库，此时不会出现打开对话框。

选择 Open Library 命令，EndNote 会出现一个对话框。

EndNote默认显示 ENL, ENLX, 或 LIB 等扩展名文件。如果数据库文件扩展名不是上述3个，打开选项可以选择「All files (\*.\*)」。找到数据库的保存位置打开即可。

如果打开的是EndNote压缩备份文件(扩展名为.ENLX)，EndNote 会自动解压压缩文件，并打开解压后的文件。参阅：[数据库压缩备份](/lib/library-operation/saving_a_cmprssdcpy_ofa_lib.md)
