Analyzing a Folder

You can use Folder Analysis to calculate the size of a folder and the number of objects in a folder.

If you use Folder Analysis to calculate the size of a folder, you will be billed for the API calls used to list objects in the bucket. For details, see Billing Description.

Constraints

Only folders with no more than 1 million objects can be analyzed. If your folder contains more objects than that, use the listing objects command of obsutil for analysis.
It may take some time to analyze folders with a lot of objects.

Ways to Use Folder Analysis

You can use OBS Console or obsutil to analyze a folder.

Using OBS Console

In the navigation pane of OBS Console, choose Object Storage.
In the bucket list of OBS Console, click the desired bucket to go to the Objects page.
Click Analyze in the Operation column of the folder, or click in the Size column.
Click Task Center on the right corner of the page, and check the analysis result on the Analyze tab.

You can see information such as the bucket that a folder belongs to, the size of the folder, the number of objects in the folder, and the analysis status.

Counting the number of objects in a folder

obsutil cannot be directly used to obtain the number and size of objects in a folder. You need to list objects.

Querying the folder size

Take Linux OS as an example. Run the ./obsutil ls obs://bucket-test/test/ -du -limit=0 command to query the size of the test folder in bucket bucket-test.

./obsutil ls obs://bucket-test/test/ -du -limit=0
