Q. offers you various possibilities to attach your own files to your tasks.
The classic way is to simply select the files from your explorer when creating new tasks or editing existing tasks and clicking the red plus button.
Another possibility is dragging the files into the tasks detail page. Here you can pull up to 10 files at the same time. Afterwards the files are uploaded in the background and are now visible in the task.
If you do not want to upload a file, you can simply stop the upload.
If you want to delete your uploaded files, click on the three small dots next to the task and then on "Edit".
