Symptoms
While copying files, Sharegate displays the following message:
Unable to copy your file. This file type is blocked by SharePoint due to security risks.
Error code
- Any error code ending in -010
Details
This message is displayed when the destination or source SharePoint server blocks the copy of a file because it has a restricted extension. This occurs because SharePoint has a built-in list of file extensions which might pose a security risk for your SharePoint environment.
Solution
You can either modify the extension of the source file or modify the list of blocked extensions at the destination (for on-premises environments only).
To add or remove blocked file types using Central Administration:
-
Verify that you have the correct administrative credentials (you must be a Farm Administrator on the server).
-
In Central Administration, click Security.
-
On the Security page, in the General Security section, click Define blocked file types.
-
Go to the Web Application menu.
-
Click Change Web Application.
-
Select a web application.
-
Do one of the following:
-
To block an additional file type, scroll to the bottom of the Type each file extension on a separate line text box, and type the file extension you want to block, and then click OK.
-
To stop blocking a file type, select a file type from the list, press the delete key, and then click OK.
