To allow other computers to share files/folders/directories on Raspberry Pi, install samba,

$ apt-get install samba samba-common-bin

To set up a network share folder, add a section at the end of smb.conf,

$ nano /etc/samba/smb.conf

# workgroup = WORKGROUP wins support = yes # [shared_folder] Comment = some description Path = folder_path Browseable = yes Writeable = Yes only guest = no create mask = 0777 directory mask = 0777 Public = yes # write list = pi, root, @lpadmin

The configuration will take effect only when the samba service is restarted.

$ systemctl restart smbd.service

The example above allows complete read/write permissions to the public. Change them according to specific needs for each. Some settings, for instance the commented-out line, do not seem to work with Windows 7. A file located in the shared_folder can be edited/deleted on Windows 7 if its attribute is set as follows:

$ chmod 777 file_to_be_edited_in_windows7

To allow other systems to use the shared folders, use the following commands to add a user:

$ smbpasswd -a user # add user with password
New SMB password: password 
Retype new SMB password: password

To list all samba users:

$ pdbedit -L

To delete a user:

$ pdbedit -x -u user
