Editing Object Properties
The properties of an object include the object details, permissions, and metadata that you set when you uploaded the object. You can edit these properties at any time.
This section explains the properties of an object that you can change and includes the object's details, permissions, and metadata.
To access the properties of an object
In the Objects and Folders list, click the object.
Do any or all of the following:
To edit the object details, click Details, and then edit the details as explained in Editing Object Details
To edit object permissions, click Permissions, and then edit the permissions as explained in Editing Object Permissions.
To edit object metadata, click Metadata, and then edit the permissions as explained in Editing Object Metadata.
When you select a single object in a bucket you can change all of its properties. When you select multiple objects, you can change only the object details.
Editing Object Details
This section explains how to use the console to edit the details of one or more selected objects. The property details of an object that you see and can change depends on the storage class of the object:
Standard and Reduced Redundancy Storage (RRS) Class— When an object is in the Standard or RRS storage class, the properties of an object you can see and change include the object's storage redundancy and the state of server-side encryption. In general, you use Amazon S3 RRS to reduce costs by storing non-critical, reproducible data at lower levels of redundancy than Amazon S3's standard storage. For more information, see Using Reduced Redundancy Storage. You can use server-side encryption to encrypt objects at rest. For more information, see Using Encryption.
Glacier Storage Class—When an object is in the Glacier storage class, the properties of the object are view-only if the object has not been restored. When the object is restored, you can modify the date until which the object is restored. In general, you assign objects to the Glacier storage class for archival purposes and you don't need real-time access to them. For more information, see Object Archival (Glacier Storage Class).
Standard and Reduced Redundancy Storage Class
When you select an object stored in the Standard or Reduced Redundancy Storage (RRS) class and click Details, the details become visible. You can change the Storage Class property or Server Side Encryption property of the object and click Save to save change to the properties. The following example shows the details for an object.
When you select two or more objects in a bucket and click Details, no selections for Storage or Server Side Encryption are shown, regardless of the settings of these properties for the files that are part of the selection. In this multiple object select case, the Details panel enables you to change one of the two properties for all of the selected objects. For example, if you select AES-256 for Server Side Encryption and click Save, then all of the selected objects will be encrypted. The following example shows the details for two selected items.
Glacier Storage Class
When you select an object stored in the Glacier Storage class and click Details, the details appear. If the object has not been restored, the properties of the object are view-only. The following example shows the details properties for an object stored in the Glacier storage class that has not been restored.
If the object is in the process of being restored, the Details tab indicates this. The following example shows the properties for an object stored in the Glacier storage class that is in the process of being restored. For more information about restoring, see Restoring an Object.
If the object is restored, the date until which the object is restored is displayed in the Details. The following example shows properties of a restored object. You can use the Modify button to change the length of time until which the object is restored.
When you select two or more Glacier Storage Class class objects in a bucket and view the Properties of the selected objects, the Properties pane shows only the bucket name and the number of objects selected.
