How can I delete file I previously updated on ticket comment ?

Hi Cesare! Thanks for reaching out. Just to clarify, are you asking to remove a file you attached to a ticket? To remove a file you previously attached to a ticket, navigate to the ticket and look for the "Attachments" sub-tab on the ticket (between "Activity" and "Related Tickets"). Then, click the red "trash" icon next to the attachment you added in the comment previously. This will remove the file from Assembla! Does that help? Feel free to add a comment here or reach out directly to our support team at support@assembla.com if there's any more we can do to help! -Matthew from Assembla
