    Tags are key-value pairs provided by Tencent Cloud for easy resource identification. You can use tags to categorize and manage cloud resources. Tencent Cloud will not use your tags, they are solely used by you to manage your resources. This document describes how to edit tags for file storage resources.

    Note the following limits when editing tags:

    • Quantity: each file system allows up to 50 tags.
    • Tag key:A tag key can only contain numbers, letters, and +=.@-. It cannot exceed 255 characters in length.
    • Tag value: a tag value can only contain empty strings or numbers, letters, and +=.@-. It cannot exceed 127 characters in length.

    Directions and Use Cases

    Use case

    A company has purchased 6 file systems, of which the business group, scope and owners are as follows:

    cfs-abcdef3 Games Game A Jane Smith
    cfs-abcdef4 Games Game B Ada

    Similarly, you can add tag key-value pairs to other file systems based on the business group, scope and owners.

    3. In the “Create File System” pop-up window, find Tag down below, and click Add to add a tag to the file system. Only existing tags can be added in this step.

    4. Click OK, and the tag will be bound to the created file system.
