What needs to be clarified
Build an evidence-supported timeline for the folder, compare local and supplied cloud logs, and assess recovery options without altering original media.
Materials to prepare
- Laptop or verified disk image with acquisition record and hashes
- Cloud audit export and time-zone information
- Sync settings, missing-file list and available backups
What to compare
Use a working copy, recording hashes and tool versions. Examine client logs, file-system records, recycle bins and available document versions. Normalise timestamps with stated assumptions; correlate devices by identifiers, identifying logging gaps and effects of subsequent use.
Possible outcome of the analysis
A timeline, found or recovered-file inventory and supported technical explanations may result. A recorded account login is not treated as identification of a particular person.
Limits of the conclusions
Continued use and automatic cleanup may destroy traces. Local logs do not cover all cloud history; attributing human actions needs evidence beyond an account entry.
