Attachments on items and models
Attachments allow you to add useful information to items and item models, such as images, care instructions, and user manuals. This makes items easier to identify, use, and maintain.
In addition to items, attachments can also be added to reservations, maintenances, projects, and productions.
Users with editor rights for the Items module can add attachments to both individual items and item models.
- Files added to a model are automatically shown for all items of that model
- Files added to an individual item are shown only on that item

⭐ Tips
- You can add up to 10 files at a time
- Changes made to files are not automatically saved in Trail. If you update a file, save the updated version on your device and upload the new version to Trail
- Use clear file names, for example User_manual_XYZ.pdf
- Use images to make items easier to identify. You can also add a photo showing where the label is attached to the item, making the label easier to find
