1. Description / Summary

When listing files and the source is specified this way, it generates an out of range error:

dds ls -p project_1 -f /

This is due to the code striping the last trailing character to properly process folder names. The command above should, therefore be equal to

dds ls -p project1 -f . or dds ls -p project! -f ./

This PR solves this issues and patch this.
