How can I copy a file from one directory to another in DBFS using dbutils.fs.cp?
You can use the `dbutils.fs.cp` command to copy a file from one directory to another in DBFS. Here's an example:
```python
dbutils.fs.cp("/path/to/source/file", "/path/to/destination/file")
```
Replace `/path/to/source/file` with the path of the file you want to copy and `/path/to/destination/file` with the path where you want to copy the file to. The command will return `True` if the copy operation is successful, and `False` otherwise.

For example, if you want to copy a file named `data.csv` from `/Volumes/main/default/my-volume/` to `/Volumes/main/default/my-volume/new-data.csv`, you can use the following command:
```python
dbutils.fs.cp("/Volumes/main/default/my-volume/data.csv", "/Volumes/main/default/my-volume/new-data.csv")
```
This will copy the `data.csv` file to `new-data.csv` in the same volume.
