“Too many open files” – can’t remove a directory

I’ve created a large tree of empty directories in an Android emulator, around 1024.

Now whenever I try to remove it with rm -rf 1/ I get a “Too many open files” error. How can I remove it?

Answer

1. Please try to use ulimit to set the open file handle as 4000 or more, you can use “ulimit -a” to show the current limitation of open files.
2. Please remove the deepest folder first, then rm them one by one
