Android 内存问题，知道的来！！

[karonl]

手机提示空间不够不足以安装新的软件，那么问题来了，手机内置存储那么多g都存储了些什么东西？
手机有ram，rom，sd，还有什么存储空间么？

[karonl]

@fxdmt 有所了解，我就是找了个小到rom，效果还是可以看出来到。你到意思所内置sd卡外到东西就是系统到东西，也就是root看到到东西吗？

[karonl]

@icedx 能看到这些分区到大小吗？

[icedx]

@karonl 能

@karonl 是的
有一部分手机的内置sd卡是/data分区下的特殊目录，我的荣耀3c在/data/media/0这个目录下
而有一部分手机的内置sd卡是单独分区的，就像电脑中的c d e f分区一样
