Ubuntu - add a folder to bookmarks on the left panel

Bookmarking a folder on Ubuntu is easier as expected: just open the folder you want to have at hand in the left-hand-side panel, and from the above menu choose Bookmarks, and then Add Bookmark. In alternative, directly from the folder press CTRL+D, and a shortcut will be created in the bookmarks tab.

Ubuntu: sharing folders with Windows

These simple steps are taken from the Ubuntu Official Documentation:

1. Press Applications → Accessories → Terminal to open a Terminal.
2. Type shares-admin and press Enter to open Shared Folders.
3. You may receive a message which says Sharing services are not installed. If this happens, ensure that the two checkboxes in the message box are checked and press Install services. Sharing service support will then be downloaded and installed; this may take a while.
4. Press the  button and enter your password in the Password field.
5. Press the Authenticate button.
6. Select the Shared Folders tab and press Add.
7. Select the location of the folder you wish to share by changing the Path option.
8. Choose Windows networks (SMB) from the Share through option.
9. Enter a name and comment for the shared folder.
10. If you would like people accessing the shared folder to be able to add, change and remove files in the folder, uncheck Read only. If you leave Read only checked, people will only be able to view files in the folder.
11. Press Share to make the shared folder available. Other people on the same network (LAN) as you should now be able to access the folder.

Maybe the Windows pc has to be restarted...
