Prioritize using the app's own export or sync functions, and then confirm that the output format can be read elsewhere. Screenshots are only suitable for a small amount of auxiliary retention.
Understand the essentials
Different applications may export text, PDF or specialized formats, and specialized formats may still require the original software.
A practical example
Hypothetical example: If you see notes in your account but cannot open them offline, you should export the universal version.
What to check or try
- Select a few test notes.
- Export and retrieve.
- Check pictures and attachments.
- Check the ordering and text encoding.
- Process in batches again.
Different formats serve different purposes: universal formats for easy reading, backups supported by the original application for continued editing. Keep it when conditions permit, and write down which software is needed for recovery. You cannot assume that the data has been saved independently just by seeing the export button appear.
An easy-to-miss detail
Verify the sample first and then operate everything to avoid batch export and then discover that attachments are missing.
