(large) file transfer challenges: the files are corrupted, files are missing, MFA time out
Very large files
Very large files use a different transfer mechanism in the background to reduce the time needed for upload. For this a temporarily storage location is used (safe, secure, encrypted).
The downside is that the files must be moved to the Workspace afterwards and this can take time. Trying to use or copy the file prior to completion can result in a corrupt file.
Even when you see the file(s), wait till you are notified by email that the transfer is completed.
This deals with the problem that:
- Files/folders are missing
- Files are corrupted
When you do encounter this problem, delete and upload again.
Potential other causes for failed uploads
- Not waiting till you see that all files/folders are uploaded 100%
- Very long folders/file lengths
- Special characters in the folder or file name, the '+'-sign is notorious
Alternative upload mechanism
Use an external program like Microsoft's Azure Storage Explorer.
Requirement:
- Download and install Azure Storage Explorer on your local machine
