Windows network shares can be accessed from Linux using CIFS/SMB. This is useful when a Linux machine needs to read or write files on a Windows share or NAS.
Install CIFS tools
sudo apt install cifs-utils
Create a mount point
sudo mkdir -p /mnt/windows-share
Mount the share manually
sudo mount -t cifs //server/share /mnt/windows-share -o username=myuser
You will normally be prompted for the password. Avoid putting passwords directly into commands or shell history.
Unmount when finished
sudo umount /mnt/windows-share
For permanent mounts, use a protected credentials file and update /etc/fstab carefully. Test manual mounting first before making boot-time changes.
