Alibaba Cloud

Mount an Alibaba Cloud OSS (Object Storage Service) bucket as a Windows drive.

Before you begin

You need an AccessKey ID and AccessKey Secret with permission to list and read/write the target bucket.

Where to get the keys — in RAM AccessKey Management: create a RAM user (recommended over the root account), attach an OSS policy (e.g. AliyunOSSFullAccess or a scoped custom policy), then Create AccessKey and copy both values.

Help from Alibaba Cloud

• Create an AccessKey pair
• OSS documentation
• OSS console

Connect

1. Click Add in the toolbar.
2. Choose Enterprise → Alibaba Cloud.
3. Enter the AccessKey ID as Access Key ID and the AccessKey Secret as Secret Access Key, then click the Refresh button next to the bucket field.
4. Select the bucket and click Connect.

Manual bucket entry

If your key is not allowed to list buckets, tick the checkbox to the left of the bucket field and type the bucket name directly.

Settings

Setting	Description	Default
Access Key ID / Secret Access Key	RAM or account credentials (Alibaba's AccessKey ID/Secret)	—
Bucket	The bucket to mount (list or manual entry)	—
Read-only	Blocks writes to the mounted drive	off

Behavior & limits

• Buckets are discovered across OSS regions (oss-<region>.aliyuncs.com — mainland China, Hong Kong, APAC, EU, US, Middle East).
• S3 semantics: renaming a large folder tree copies and deletes every object under the prefix.

Troubleshooting

Symptom	Cause	Fix
Bucket list empty	RAM user lacks oss:ListBuckets	Extend the RAM policy, or type the bucket manually
Access Denied on connect	Key lacks bucket permission	Check the bucket ACL/policy in the OSS console
