CalcLockAt a glance: Use your own trusted PC and a data-capable cable, import a small sample first, then verify the destination files independently of the phone.
Decide where the files should land
Before connecting the phone, choose a destination folder on a computer you control. Give the folder a clear date or event label, and check whether it belongs to a shared Windows account or a cloud-synchronized location. Copying private photos to a family desktop is not automatically a privacy improvement. The destination needs appropriate access protection of its own.
Estimate the size of the group you want to copy and make room for it. Start with a few photos and a video whose contents you recognize. A small rehearsal tells you where the import lands and whether you can open the formats before a long transfer leaves hundreds of uncertain results.
Connect through the supported route
Apple’s Windows instructions call for the Apple Devices app from the Microsoft Store and a USB connection. Use a cable that supports data transfer, not merely charging. Unlock your iPhone and read any Trust This Computer prompt. Approve that relationship only for the computer you intended to use and actually control.
Microsoft’s Photos app provides Import, followed by your connected device. Choose the intended items and destination, then allow detection and transfer to finish. Keep the phone connected and avoid changing unrelated synchronization settings during this first test. Importing to a folder and configuring ongoing phone synchronization are different tasks.
Resolve cloud-only sources before retrying
Apple notes that when iCloud Photos is enabled, the full-resolution originals must be downloaded to the iPhone before importing them to a PC by this route. Seeing the photo on the phone is not enough if you are viewing an optimized local representation. Prepare the sources while you have a reliable connection and enough space.
If some expected items are missing from the import selection, first establish whether they are available locally and included in the source library you meant to copy. Do not repeatedly select everything or delete earlier attempts without inspecting them. A partial transfer can leave useful files alongside missing ones.
Verify the PC copy without the phone
After the import completes, locate the actual destination folder in File Explorer. Open several images at full size and play the test video, including its ending and audio. Compare identifiable details with the source. Check the number of expected files, but remember that matching totals do not prove every intended image arrived.
Disconnect the phone after transfer is complete and open the destination files again. This practical check helps confirm that you are viewing the PC copies rather than relying on the connected device. If a file will not display, investigate format support before concluding that its data is missing. Do not rename an extension as an attempted conversion.
Expand the transfer and retain a useful record
Proceed in understandable groups and record the source period, destination, and any failures. Keep original files unchanged while you establish that the archive is complete. If you later make JPEG versions for compatibility, store those as derivatives rather than silently replacing the source collection.
This process copies sources available outside CalcLock. It does not export encrypted vault contents or create a CalcLock restore package. Keep the verified PC archive independently protected, and consider a separate additional copy for irreplaceable material before removing anything from the phone. A single successful cable transfer is a useful first step, not a lifetime retention plan.
Questions, answered
Does the Most Compatible camera setting convert my old photos?
No. Apple describes it as a choice for future captures. Existing files need their own verified conversion workflow if a destination cannot use their format.
Should I approve Trust on a borrowed or public PC?
Avoid using an untrusted computer for a private photo archive. Choose a device you control and understand before approving access.
