# Library

Manage uploaded, transferred or certified files

[Library](https://app.aetrna.cloud/library) feature is designed to fetch the list of uploaded files, reconstruct download keys and co-sign the certified documents.&#x20;

In Library you can:

1. See the metadata of your files (Timestamp, Certification state, Size, Name, etc)
2. Directly download files
3. Get the metadata of your files
4. Co-sign a certified document
5. Generate a confirmation e-mail as Initiator and Co-signer
6. Add an NFT to your wallet
