Shared folders in Synology DiskStation Manager

How to create a shared folder on Synology NAS

Before doing anything on a Synology NAS, it’s vital to set up at least one shared folder. Shared folders are used by the NAS operating system to store data. In this guide, I’ll explain precisely what shared folders are and how to quickly create them.

What is a shared folder?

Shared folders are how Synology’s DiskStation Manager (DSM) handles storing data on a NAS. Think of them as Linux, macOS, or Windows folders on a PC. Two types can be used on a Synology NAS enclosure: shared folder and hybrid shared folder.

The former is the basic directory for storing files and the latter is used by the Synology C2 cloud platform. If you’re not going to be utilizing Synology’s cloud services, I’d recommend creating normal shared folders. Some services and apps will even create them for you.

How to create a shared folder

Creating a shared folder on a Synology NAS enclosure couldn’t be easier. Simply follow these steps:

  1. Log into your Synology NAS.
  2. Go to Control Panel > Shared Folder.

During the creation of the shared folder, a few options are available:

  • Hide this shared folder in “My Network Places” to prevent the shared folder from being listed within Network on Windows File Explorer.
  • Hide sub-folders and files from users without permissions to prevent the shared folder from being listed to those without adequate permissions. (Only available with SMB, AFP, and File Station.)
  • Enable Recycle Bin to … well, enable the recycle bin.
  • Protect this shared folder by encrypting it to provide additional security.
  • Protect this shared folder with WriteOnce to shield it from being modified, deleted, or renamed for a specified period.
  • Enable data checksum for advanced data integrity using CRC32 checksum and copy-on-write to protect the shared folder.
  • Enable file compression to have files automatically compressed to save space.
  • Enable shared folder quota to specify the maximum capacity for this shared folder.
