Files and Attachments are backed up in separate root folders that are found together with the Objects folder.
The Attachments folder contains files that were attached to records in Salesforce Classic.
The Files folder contains files that were attached to record in Lightning Experience and files that were uploaded to Files in a Salesforce organization.
There is no option to restore the items in these folders individually.
To recover files and attachments, you have two options:
- Download the file or attachment and then manually upload it back to Salesforce
- If the file or attachment is attached to a record, restore the record to automatically bring back the file or attachment.
Inside the Objects folder, there is also an Attachments folder. The items are the same as those in the Attachments root folder but here the items only contain the metadata of the attachments. These items can be restored but no content will be recovered.
