Adding files from your computer

Anywhere you see the text editor in Basecamp 3, you can attach a file one of two ways:

1. Add from your computer: click the paperclip icon and then select a file from your computer. Be sure to click the green save changes button before you leave the page so that your message and file upload properly.

2. Drag and drop: drag a file from anywhere on your computer and drop it onto the page where the text editor is open. The file will appear where your cursor is, so be sure the cursor is in the place where you want the file.

Note: Image files (PNG, JPG, GIF) will appear with previews in your browser.

To delete a file attached to an item, click to edit the item (top left) and then click "•••" and Put this in trash. You'll then be taken to a page confirming that the file was deleted.
