 You can save the name of files in a directory like this:
 
 ```shell
-> ls | where type == File | pick name | save
+> ls | where type == File | pick name | save filenames.csv
 ```
 
 Or you can format it in supported formats using one of the `to-*` commands:
 
 ```shell
-> ls | where type == File | pick name | to-csv | save
-```
\ No newline at end of file
+> ls | where type == File | pick name | to-csv | save filenames
+```
+
+`filename.csv` and `filenames` are both `csv` formatted files. Nu auto-converts the format if a supported file extension is given.
\ No newline at end of file
