If the file is known, the upload space will be calculated according to the actual length of the file.
If it is a newly uploaded file, the length will be estimated based on the file size: 1MB=1min.
Upload space limit for free users:
1. The total file size should not exceed 500MB
2. The total length of the file should not exceed 5 hours.
If any limit is reached, the user can no longer upload files.
Total file length = actual used length + estimated length < 18000 seconds
