Single quotes in folder or file names were causing corruption of the shell command.
The fix changes the ' character to '"'"'
For example a folder called te'st would now get shellQuoted to 'te'"'"'st'
1. ' ends the first quote,
2. " starts second quote,
3. ' is valid character in double quotes
4. " ends the second quote
5. ' starts the third quote
6. The end result when fed into the shell, is as we desired: te'st
