I want to only get files that start the number 1.  
ie 1*.xyz

But when I filter for +*/1*.xyz, I also get random files from folders that
include "1" in the foldername.  

ie.
[PATH]/1/201.xyz
[PATH]/A/1/301.xyz
[PATH]/A/101.xyz
[PATH]/B/1.xyz

In this example, how can I filter only the 101.xyz and 1.xyz?
Thank you.
