Engineer Analysis

Excel files (.xlsx, .xlsm, .xlsb) are XML-based ZIP archives storing data, formatting, and formulas. W a file is overwritten: www.sosit.com.cn

• Original XML components may remain on disk sectors but are partially replaced.
• Recovery success depends on storage medium, overwrite size, and presence of backups or snapshots.
• Professional recovery prioritizes critical tables, pivot tables, and formulas over cosmetic formatting.

Safe recovery requires avoiding further writes to the affected storage dev and using specialized tools or professional servs to maximize the chance of restoring original data.

Common Causes of Excel File Overwrites

1. Human error during copying or “Save As” operations.
2. Cloud sync conflicts with OneDrive, SharePoint, or Google Drive.
3. Hardware interruptions on NAS, RAID, SSD, or external HDDs.
4. Batch replacements of multiple files simultaneously.
5. System crashes during file write operations.
