Files in Channels

Files in Channels

Files and channels are deeply integrated. Share, preview, and collaborate without switching contexts.

Sharing Files

• Paste a link — Coline automatically unfurls file previews
• Upload — Drag and drop directly into messages
• Create — Make new files from the attachment menu
• Reference — Use [[filename]] to link to files inline

File Previews

Most file types render inline:

• Docs, Notes — Full preview with scroll
• Sheets — First rows visible
• Boards — Card count and status
• Images & Video — Direct embed
• Code — Syntax highlighted snippets

Collaboration

• Comments — Discuss files without leaving the channel
• Live cursors — See who's viewing files in real-time
• Permissions — Channel access doesn't grant file access; files respect their own permissions
• Versions — File history is preserved and accessible
