大家都知道Win7系统是不支持直接对CR2文件显示缩略图的，如果您想让Win7显示CR2文件缩略图那么就需要单独下载cr2缩略图补丁安装一下，这其实就是一个佳能数码相机RAW文件CR2原片格式缩略图显示补丁，下载解压直接安装即可。

CR2是佳能相机RAW格式文件，正因为佳能数码相机所拍摄的照片是RAW格式的，其中一个扩展名为.CR2的文件，在日常摄影底片管理中，没有缩略图非常不方便怎么办?

其实安装一个CR2缩略图补丁系统的资源管理器就能正常显示缩略图了，这是佳能数码相机的原始格式缩略图补丁，适用于佳能各型号相机原始格式显示。

压缩包中包含了3个cr2缩略图补丁，都能实现cr2缩略图显示。

cr2codec.exe

MicrosoftCameraCodecPack-x64.msi

MicrosoftCameraCodecPack-x86.msi

大家安装哪个都能，安装补丁即可直接在Windows窗口中显示CR2文件的缩略图了。

本cr2缩略图补丁提供对以下设备格式的支持：
