1. Keep the folder structure simple
Create three folders named Reading, Maps and Instructions. Put a short README in the top level describing each folder, the device used for the check and the date. These names are an original example, not a software requirement.
Do not mix personal recovery codes or sensitive notebooks into a public reference folder. Label private encrypted backups separately and test their own recovery process. A filename containing “private” does not encrypt a file.
2. Match files to readers
A standalone HTML guide can open in a browser. A PMTiles map needs a compatible map reader; a ZIM archive needs a compatible archive reader. Saving any of those files does not install the other reader automatically.
Google’s Files documentation explains USB use on supported Android devices. Phone ports, adapters, drive formats and power needs still vary. Confirm the intended phone can access the drive instead of assuming a desktop opening test proves phone compatibility.

3. Test the smallest useful set
Record each file’s actual size and source date. Choose a guide you can open without signing in. Safely eject the drive, reconnect it and open the file from the drive with internet disconnected; do not rely on a browser tab already loaded.
If the reader is missing or the file does not open, mark the result as unresolved. Keep a paper pointer to the folder names. Add large map or encyclopedia archives only after this simple test works.

One reading file, 5.0 KB. No maps, external images, scripts or personal records. External source links still need internet.
Checks remain only during this visit. They do not certify readiness, safe equipment or successful delivery. The saved worksheet has blank prompts.
Save on this computer, or copy the completed download to a compatible USB drive. Reopen from that location for the offline test.
READ THE BASIS
Sources, dates and limits
A folder plan does not scan a USB drive for malware or guarantee compatibility. Use trusted files; do not run unknown software from a found drive. Maps and private backups are separate files.
Source links checked October 11, 2026. The organization and sample worksheets are original editorial work. A source check is not a qualified review or a physical-device test. Downloaded files are dated snapshots; use current local guidance and equipment instructions.
