The OSS Browser.js SDK provides several ways to manage files (objects) in a bucket. You can choose a method from the following list based on your business scenario:
To view information about all files in a bucket or the files and subdirectories in a specific folder, you can list the files. For more information, see List files (Browser.js SDK).
To copy a file from a bucket to the same or a different bucket in the same region, you can use the copy operation. For more information, see Copy files (Browser.js SDK).
To avoid overwriting existing files with the same name during an upload or copy operation, you can prevent the files from being overwritten. For more information, see Prevent overwriting files with the same name (Browser.js SDK).
To read Archive or Cold Archive files, you must first restore them. For more information, see Restore files (Browser.js SDK).
To quickly access frequently used files in a bucket, you can create symbolic links to the source files. For more information, see Manage symbolic links (Browser.js SDK).
To identify the purpose or properties of a file, you can specify file metadata when you upload the file. For more information, see Manage file metadata (Browser.js SDK).
