All members of a group conversation can share files and delete files in the group’s shared folder.
Share files either by dragging and dropping them on the main chat conversation or by clicking the upload files button in the file overview screen.
If the shared file is an image, a thumbnail of the image will be generated and displayed. For any security conscious people out there, it might be comforting to know that the thumbnail is generated on the client while uploading. Generating thumbnails on the server is of course impossible, as all files are encrypted before they reach Crypho’s server.
Viewing shared files
When someone shares a file in a conversation, it is immediately displayed in the chat and available for download. Clicking a file icon or thumbnail immediately downloads and decrypts the file to make it available to you.
All the shared files can also be seen in the “Files” panel. Delete files in the shared files panel by clicking the trash icon.
File size limits
File uploads have a max size depending on your account plan. Free account can share files up to 3 megabytes. Paid accounts can share files up to 100 megabytes, depending on plan size.
