Bugfix on folder spaces

In future, in case you need to revert back to default in some function, you can always use unset IFS to remove the modifications.

This is how it was before:

You can check the changes in code (it's just one line) in the files changed tab in the PR and let me know if I should make any more changes. Thank You!
