A whole generation has grown up with their lives recorded in digital form–photos, videos, class assignments, social interactions. For the digital files that are important to last, the creator must actively manage them. Digital files are vulnerable to loss from either human error (failure to be vigilant), natural disaster (hard drive failure or bitrot) or just plain neglect—unstable file formats, poor file naming, or failure to have multiple copies or move a file from a device before replacing that device.
People get new phones and new devices on average every two years. In order for digital files to persist, people can take some common, relatively painless actions. Firstly, because machines or devices may break, you should always keep multiple copies of files on different devices. If your phone has an option to back up your files to a cloud provider e.g. icloud or GoogleDrive, you should opt to do that. Additionally, we suggest you back up your device to a computer. As you run out of space on your device, you can transfer those to another machine that to delete them from your device. Second, not all file formats are equal. In the world of digital persistence, some file formats are more universally supported and can be read by different types of machines while others are closed and require a specific piece of hard ware and software to read them. For a list of recommended file formats, please consult our guidance document, “File Format Guidelines for Management and Long-Term Retention of Electronic Records.”
Last, when a machine or device saves a file, it typically either assigns it a name or will ask you to name it. If you don’t consciously name it something that will make sense to you now and in the future, you risk losing important files because you cannot remember the name of the file. This is particularly true with digital photos which inherit the name assigned to it by the SIM card. By renaming the file and organizing it according to function or event, you will better be able to discover it in the future. For more guidance on File Naming, please consult our guidance materials, “Best Practices for File Naming” or video tutorials on File Naming at https://www.youtube.com/watch?v=Hi_A4Ywn4VU&feature=youtu.be.
