This guide provides documentation for Wickr Enterprise. If you're using AWS Wickr, see [AWS Wickr Administration Guide](https://docs.aws.amazon.com/wickr/latest/adminguide/what-is-wickr.html). # Messaging The **Messaging** section has the following available features for users: + **Send Link Preview:** This allows a user to send or receive previews for URLs sent within Wickr. The preview is generated from the sending device. Recipients will not connect to the underlying URL until selected. + **Location Sharing:** Allows users to share a link to their GPS coordinates in the app. + **Map Sharing:** If enabled with **Location Sharing**, it will allow a user to send a map with their location. This map can be shared for a pre-determined amount of time that will update as the user moves. + **File Attachment & Voice Memo:** If disabled, users will be unable to send attachments or voice memos. This also prevents downloading attachments sent by others in rooms, groups, or DMs. The **Messaging** section has the following additional features: + **Secure Shredder:** The Wickr shredder will write random data over free memory and disk space on client devices. For more information on how to configure your Secure Shredder intensity, see [ShredderSettings](https://docs.aws.amazon.com/wickr/latest/APIReference/API_ShredderSettings.html) in the *AWS Wickr API Reference*. + **Bot Read Receipts:** Allows bots to automatically “read” messages in a room instead of requiring users to @ the bot for interaction. + **Image/File Download Size:** By default, it will upload and download the file uncompressed. If compression is enabled the apps will attempt to compress the data before encrypting and uploading. + **Auto-Destruct:** This is the default maximum for any message sent within the network. Users can adjust to any amount lower than this value. + **Quick Responses:** Allows administrators to set pre-filled messages that users can send by clicking within the app. Each quick response supports up to 8,000 characters, including formatting and emoji. Only ten are allowed per group. + **Maximum Upload Size:** This is the default maximum number of bytes allowed for an upload within the network.
