Revisions of a document
To view of upload a new revision of a document, you can use the top right versions menu, and select the version you want to preview or upload a new revision.
File metadata
You can view the metadata of a file by clicking on the "i" info circled icon. This will give you:
- The bucket where the object is stored
- Its key

- its Etag
- its CRC32 checksum
The CRC32 checksum will be available only if:
- The document was uploaded from the portal after July 10th, 2025
- It was uploaded through an API integration or CLI or via AWS SDK, passing the correct parameters ( see Check object integrity.)
