## Troubleshooting Paths

### Login fails or user does not exist

1. Confirm whether you should use the public cloud login, enterprise subdomain or private-cloud domain.
2. Confirm that the account is the email or phone number assigned by the administrator.
3. Private-cloud users should use the private-cloud entry or the company-specific URL.
4. If it still fails, ask an administrator to check account status, department membership and initial password notifications.

### Cannot upload or create folders

1. Confirm that you are not in the enterprise-file root. Enterprise files require entering a department folder first.
2. Confirm that your department role allows upload, folder creation or project creation.
3. Check file access control, allow/deny lists, storage limits and upload-only permissions.
4. Client, sync and mapped-drive upload follow the same permission system.

### Sync or mapped drive issues

1. Confirm that the client is logged into the correct enterprise and the sync or mapped-drive task is running.
2. Check local path, cloud path, sync direction, sync blacklist and file permissions.
3. If conflicts or partial failures occur, identify the latest local and cloud versions before overwriting, restoring or uploading a new version.
4. Mapped drives depend more on live network and permissions; sync folders are better for offline editing and long-term local work directories.

### Share link fails or permissions look wrong

1. Check whether the share expired, was closed, was restricted by administrators or requires enterprise-member access.
2. Check whether the share allows preview, download, edit, comment or upload.
3. If external sharing approval is enabled for department or personal files, wait for approval.
4. Files inside encrypted folders still require the encrypted folder password even if the share link is available.

### Online editing or preview issues

1. Confirm that the file format is supported. Office online editing also depends on OnlyOffice or the online Office module.
2. Large files, complex PPT files, CAD files and video transcoding may take time to generate previews.
3. If the file is locked, confirm whether someone is editing it and ask an administrator to unlock it if needed.
4. If preview generation is stuck, check transcoding service, file format, file size and browser compatibility.
