Hi @R1zwan, the test cases are a bit tricky for this stage:

 ![image](https://canada1.discourse-cdn.com/flex003/uploads/codecrafters/original/2X/9/917e42856921ff928fd907eb88c107a950d9cf4c.png)

`"/tmp/foo/'f 64'"` will be evaluated to `/tmp/foo/'f 64'` instead of `/tmp/foo/f 64`. Note that the single quotes are part of the file name.

* * *

You verify this by running these commands:

```auto
mkdir /tmp/foo
touch "/tmp/foo/'f 64'"
realpath "/tmp/foo/'f 64'"

```
