# Manage a Stored Object

Click any of the stored objects in your bucket.

<br />

You will be able to perform the following operations on the object:

* View general details, such as the *name*, *size*, *modified time*, and *format* of the object.
* You can access the object directly using the secure Object URL. This URL can be copied and used in your code to satisfy your requirement.
<!--* You can enable Caching for the bucket; a **Caching URL** will be generated by Stratus. This URL can also be copied. When you access objects using this URL, they will be cached.
* You can click the **Purge Cache** button to purge the stored cache of the object.-->
* If you have enabled Versioning, you can view all the versions of the object present in the bucket.
* Provide Custom Meta Data for the object.
* Download the object
* Delete the Object


### Provide Custom Meta Data for an Object

To provide meta data for your object:

Note: The maximum size limit of characters allowed for the overall metadata is 2047 characters. The character count used to determine the size limit also includes the colon “:” special character used to define the key value pair.




1. Click the required object.
    <br />

2. Click the **Add Meta** button.
    <br />

3. The meta data you provide will be rendered and applied to the object in a **JSON key value format**. Click **Save** once you have completed adding the required data.
    <br />

Your custom meta data will be added to the object.
<br />





Note: Visit this help document for more information on this SDK method.

**Ensure the following packages are imported:**


import org.json.simple.JSONObject;



HashMap<String, String> objectMeta = new HashMap<>();
objectMeta.put("key1", "value1");
objectMeta.put("key2", "value2");
JSONObject res = object.putMeta(objectMeta);
System.out.println(res);





Note: Visit this help document for more information on this SDK method.


const objectMeta = {
 "key1": "value1" ,
 "key2": "value2" 
};
const objMeta = await objectIns.putMeta(objectMeta);
console.log(objMeta);




Note: Visit this help document for more information on this SDK method.


res = object_ins.put_meta({'author': 'Amelia Burrows'})
print(res)






### Edit Custom Meta Data

To edit the custom meta data:

1. Click **Modify Meta**.
    <br />

2. Make the required changes and click **Save**.
    <br />

The changes will be applied.

# Download an Object From a Bucket

To download an object from the bucket:




1. Click or select the required object.
    <br />

2. Click **Download**.
    <br />

3. Click **Save** in your system prompt.
    <br />

The object will be downloaded to your local system.

You can also download the object using the **Download** button present in the object details view.

# Delete an Object From a Bucket

To delete an object from the bucket:



1. Select the required object.
    <br />

2. Click **Delete**.
    <br />

3. Click **Delete** in the prompt as well.
    <br />

The delete action will be scheduled, and it will take a short while before the operation is rendered in the console.

Delete operations can be performed on multiple objects and on multiple paths in the same manner.

You can also use the **Delete** button present in the object details view to delete the object.
<br />







Note: Visit this help document for more information on this SDK method.

**Ensure the following packages are imported:**

import org.json.simple.JSONObject;



int ttl = 200;
JSONObject deleteRes = bucket.deleteObject("objectName", "versionId", ttl); 
System.out.println(deleteRes);




Note: Visit this help document for more information on this SDK method.


const res = await bucket.deleteObject("objectName");
console.log(res);




Note: Visit this help document for more information on this SDK method.

	if let error = error {
		print("Error : \\( error )")

Note: When you perform a delete operation on an object, and if it is the only object present in the particular path, then the entire path will be deleted. An empty path cannot exist in a bucket.
