When creating new files in an SFTP folder, they are created with all permissions enabled (rwx for everyone, setuid, and sticky).

STEPS TO REPRODUCE

2. Right-click in the main veiw area > Create New > text file
3. Open the same folder in the terminal (ssh) and run `ls -lh` to see the permissions of the newly created file

OBSERVED RESULT
```
