windows下用新的ico替换旧的图标，图标一直没替换掉，怀疑是图标缓存没有完全清理。用了清理的办法也没有办法。到底怎么才能修改文件夹的图标呢？或者如何才能彻底清除缓存？
解决办法：新建文本文件，把以下内容复制进去，然后另存为.bat文件，执行，ok！
rem 关闭Windows外壳程序explorer
taskkill /f /im explorer.exe
rem 清理系统图标缓存数据库
attrib -h -s -r "%userprofile%\AppData\Local\IconCache.db"
del /f "%userprofile%\AppData\Local\IconCache.db"
attrib /s /d -h -s -r "%userprofile%\AppData\Local\Microsoft\Windows\Explorer\*"
del /f "%userprofile%\AppData\Local\Microsoft\Windows\Explorer\thumbcache_32.db"
del /f "%userprofile%\AppData\Local\Microsoft\Windows\Explorer\thumbcache_96.db"
del /f "%userprofile%\AppData\Local\Microsoft\Windows\Explorer\thumbcache_102.db"
del /f "%userprofile%\AppData\Local\Microsoft\Windows\Explorer\thumbcache_256.db"
del /f "%userprofile%\AppData\Local\Microsoft\Windows\Explorer\thumbcache_1024.db"
del /f "%userprofile%\AppData\Local\Microsoft\Windows\Explorer\thumbcache_idx.db"
del /f "%userprofile%\AppData\Local\Microsoft\Windows\Explorer\thumbcache_sr.db"
rem 清理 系统托盘记忆的图标
