Self-hosting Send

Once you update your instance, most implementations will be already setup to begin using Send. An exception to this is if you are using a non-default mapped volume for attachment storage.

The files attached to file Sends are stored in a send subdirectory of the existing attachments volume (for example, ./bwdata/core/attachments/send). This is dictated by the globalSettings__send__baseDirectory= environment variable, which has the following default configuration in global.override.env:

BashCopy
globalSettings__send__baseDirectory=/etc/bitwarden/core/attachments/send

If you want to store the files attached to file Sends in your non-default attachments volume, you will need to point globalSettings__send__baseDirectory= to the new volume. For more information, see Configure Environment Variables.
