| ossutil | A command-line tool used to manage objects and buckets. - Provides a wide range of simple and convenient commands to manage objects and buckets while high performance of operations is ensured.
- Allows you to use concurrent upload and resumable upload to upload files.
- Allows you to upload and download directories.
|
| ossbrowser | A graphical object management tool. - Provides features similar to those of Windows Explorer.
- Allows you to browse objects.
- Allows you to upload and download directories.
- Allows you to use concurrent upload and resumable upload to upload files.
- Allows you to configure authorization policies and grant permissions to RAM users on a GUI.
- Supports Windows, Linux, and macOS.
Limits: - The transmission speed and performance of ossbrowser are not as good as those of ossutil because ossbrowser is a graphical tool.
- Only objects smaller than 5 GB in size can be moved or replicated.
- You can upload a single file up to 48.8 TB in size.

| Signature tool | The OSS console provides the following signature tools: - Signature in Authorization Header
After you use the signature tool to specify the parameters, the system automatically generates a request signature and verifies the request signature. For more information, see Signature in Authorization Header. - PostObject Policy Signature
After you use the signature tool to specify the parameters, the system automatically generates a request signature for the upload by using an HTML form and verifies the request signature. For more information, see PostObject Policy Signature. - URL Signature
You can use the signature tool to generate a signed object URL for temporary access. When you generate a signed URL, you can specify the validity period of the URL to limit the period of access from visitors. For more information, see URL Signature.

| ossimport | A tool used to synchronize data to OSS. - Allows you to synchronize data from a third-party data source to OSS.
- Supports distributed deployment. You can use multiple servers to migrate data simultaneously.
- Supports migration of more than terabytes of data.
- Supports Windows and Linux.
- Applicable to Java 7.

| ossfs | A tool used to attach a bucket to the local file system. After you attach an OSS bucket to the local file system of Linux, you can perform operations on objects in the bucket to access or share these objects by using the local file system. - Supports most features of POSIX-compliant file systems, including file reads and writes, directories, link-related operations, permissions, UIDs, GIDs, and extended attributes.
- Allows you to use multipart upload to upload large files.
- Supports MD5 verification to ensure data integrity.
Limits: - Archive and Cold Archive buckets cannot be attached to local file systems by using ossfs.
- If you use ossfs to edit an uploaded object, the object is uploaded again.
- The performance of metadata-related operations such as
list directory is compromised because you must remotely access the OSS server. - Errors may occur if you rename an object or a directory. Operation failures may cause data inconsistencies.
- ossfs is unsuitable for scenarios that require highly concurrent read and write operations.
- If an OSS bucket is attached to multiple clients, you are responsible for maintaining data consistency. To prevent multiple clients from writing to the same object at the same time, we recommend that you schedule when users can use objects.
- Hard links are not supported.
|
| ossftp | An FTP-based tool used to manage objects in OSS. - You can use FTP clients such as FileZilla, WinSCP, and FlashFXP to manage objects in OSS.
- ossftp is an FTP server that receives FTP requests and performs operations on objects and directories in OSS.
- ossftp is based on Python 2.7 and later.
