Make an offline computer usable
A USB drive is only helpful when a device can open its files.
Save a small sample document, map and reference file, then confirm the computer and phone have the apps required to open each format.
Keep cables, adapters, charger and a written index with the drive. Check file-system and largest-file compatibility before copying a large archive.
Disconnect the network and reopen several files after restarting the device. Keep sensitive information in protected storage rather than public guide folders.
Keep a copy you can open.
One small HTML reading file. Opens in a browser without extra software. No maps or personal records included; source links need internet.
Save this small HTML reading file to your Desktop or USB. Reopen the actual file with internet disconnected. Source links require internet; maps and private records are separate.
