You can obtain statistics for a folder (directory) via the COS console, including the total number of objects and the total size of objects in the current folder. For details about folders and directories, see folder and directory.
Note
Object storage stores objects in a flat structure without the concept of folders. To maintain user habits, it implements "folders" by naming objects with a "/" suffix in the object key. In fact, a "folder" in object storage is an object with a storage size of 0KB.
Metadata Acceleration Bucket currently only supports statistics for folders (directories) with fewer than 100,000 files. If the number of files exceeds 100,000, it is recommended to use HDFS du command or API inventory statistics.
If you have enabled versioning, the statistics will only be calculated for the current version and will not include historical versions or delete markers. For more details, see Versioning Overview.
COS charges for List Objects and inventory on demand: List Objects request fees are incurred when using List statistics, while inventory feature fees are incurred when using inventory statistics. For details, see Product Pricing.
When a folder (directory) contains a large number of objects, the statistics process may take some time. Please wait patiently.
