File order of "For Each File" step

Question / Problem: 

In what order are files processed with "For Each File" step?

The order should be the same as how the files are listed when you list them within the system by Dir command in Windows or an LS command in Linux.

C:\test\1.txt
C:\test\2.txt
C:\test\a.txt
C:\test\b.txt
C:\test\c.txt
C:\test\f1\1.txt
C:\test\f1\11111.txt
C:\test\f1\2.txt
