In the folder properties dialog you can set the access rights for the selected folder.
On Unix-like platforms (including Linux and macOS), the file mode governs the access
rights to the installed directories. The access mode is composed of three octal numbers (0-7)
and each number completely expresses the access rights for a particular group of users:
- First number
The first octal number contains the access rights for the owner of the file.
- Second number
The first octal number contains the access rights for the user group that the
file is attached to.
- Third number
The third octal number contains the access rights for all other users.
For a desired combination of access rights, the octal number is calculated by adding:
- 1
For the right to browse the directory.
- 2
For the right to write to the directory.
- 4
For the right to read from the directory.
The default access rights for directories are 755, i.e. the owner can read and write and browse
the directory and all others can only read and browse it. Since usually applications on Unix-like systems
are installed by the administrator (usually called root), this means that except for
root, users will only be able to browse directories and read from them but they will not be able to
create files in them. If you have directories that your users should be able to create files in, you have to
set a different access mode for them. For example, 777 would allow all users to
create, read, write and delete files in the directory.
You can reset the default mode with the Reset to default button.
