If you want share files with somebody without adding them as users, Synology has a feature to do this.
IMPORTANT NOTE: For this to work, you need to be able to access your Synology from the internet.
Here is how you do it:
Go to File Station:
Select the file you want to share, right click and choose “Share file links”:
On the “Share File links” window, choose “Validity” if you want to set a specific period of time for the link to be valid:
Click on “Customize validity period” if you want to choose other than “A week” or “A month”:
If you want to secure your connection, click on “Enable secure sharing”. This will give you the option to either write a password or share it with your social network friends on Facebook or Google+.
If you decide to share with a password, enter a password on the field marked below, and if you have email configured click on “Mail” to open your mail service directly. If you haven’t an email account configured, simply copy the sharing link to any other email service and send:
If you want to share with your social network, click on “Add friends” and Synology will ask you to login into your account. Once you have logged in, you click on “Add friends”, click on OK and you are done.
Once you have set up everything, the user will click on the link you provided and will be asked to enter the password to access the file:
Once they entered the correct password, the file will be downloaded for them:
Which documents have I shared and when does the link expire?
