    File Storage NAS:View IA or Archive files

    Last Updated:Oct 09, 2026

    Use the NAS console to view files in the Infrequent Access (IA) or Archive storage class. You can also view the usage for each storage class and the last access time for each file.

    Background information

    The NAS console only allows you to view the list of files that have been dumped to Infrequent Access (IA) storage or Archive storage through the lifecycle management feature. You cannot directly browse files in General-Purpose storage. To view the specific files and directory structure in the General-Purpose storage of a NAS file system, log on to the ECS instance that has the NAS file system mounted, and browse the file directories by using commands such as ls, find, and du.

    View IA and Archive storage usage

    1. Log on to the NAS console.

    2. In the left-side navigation pane, choose Lifecycle Management > Files in IA/Archive Storage Class.

    3. In the top navigation bar, select the resource group and region where your file system resides.

    4. On the Files in IA/Archive Storage Class page, view the Usage, Usage of IA Storage Class, and Usage of Archive Storage Class for the file system.

    View IA or Archive file details

    1. Log on to the NAS console.

    2. In the left-side navigation pane, choose Lifecycle Management > Files in IA/Archive Storage Class.

    3. In the top navigation bar, select the resource group and region where your file system resides.

    4. Find the target file system and click Actions in the View Details column. Then, click the Files in IA/Archive Storage Class tab.

This view shows information for each file, including its File Name, File Size, Storage Class, and last access time. You can also view the file's total time in Archive storage and the time since its last modification.
