Know your copies before you change anything.

A practical worksheet for importing photos, reviewing storage or preparing a new phone. Mark what you have checked and keep the remaining questions in view.

01 / Know the copies
02 / Check the destination
03 / Plan for loss or change
04 / Make the final decision

What a checked box means

A tick records that you reviewed that question. It does not inspect your device, verify a backup or prove that a file can be recovered. Open a real independent copy and check it yourself before any destructive change.

For CalcLock collections

Imports make separate local copies and do not delete the originals. The app does not offer export, cloud sync, backup restoration or a forgotten-equation reset. Keep your original files. Do not use this worksheet as a reason to delete them after importing.

Before switching phones

Keep the old phone and the source files available while you set up the new one. Establish a fresh collection from retained originals rather than assuming a device backup transfers the vault. Only erase a device after you have independently verified everything you need elsewhere.
