Troubleshooting

Use two images and two viewers to separate file damage from a Photos app registration problem, then repair the correct layer without deleting the originals.

Verify that the source video is complete and local, identify its actual codec, test a clean presentation, convert only a copy, and recover missing media separately.

Use firmware detection, connection behavior, and drive stability to separate a boot-file problem from storage failure. Recover important files first, then apply the repair that matches the evidence.

Protect the original and current edits, distinguish an opening failure from a saving failure, test paths and permissions, and recover a missing version only when required.

Protect the original AEP, test Auto-Save versions and imports, distinguish project damage from missing footage, and recover deleted project copies without overwriting the working disk.

Confirm the file is a complete archive, collect every multipart volume, test a fresh copy, and recover the original only when it is genuinely missing.

Test the video in another player, identify its real codec, avoid broad codec packs, and recover the complete original only when the local file is missing.

Identify which reset or repair action requested media, recover inaccessible files first, then create official Windows media and choose the least destructive option. The workflow protects the best source and verifies the result before normal work resumes.

Use the failing action to distinguish file association, app package, COM registration, or system damage; protect inaccessible files before broad repairs. The workflow protects the best source and verifies the result before normal work resumes.

Keep the unsaved Excel session open, create a safe copy, isolate the failed path or format, and recover a lost workbook only after other copies fail.
