What is a COPY0 file?

COPY0 files mostly belong to Windows Backup Utility. COPY0 files are specific Windows backup files. They are used to store essential system data and come in two main forms:

Master File Table copy: These files hold a duplicate of the NTFS Master File Table, which helps recover the file system structure.

Registry backup: These files contain a backup of the Windows registry hive in the regf format. For additional details on registry backups, visit the Registry Explorer page.

Purpose and functionality: Windows automatically creates these files during system backup operations. They are meant to restore system settings, recover file system integrity, and assist in regaining access to the registry if needed.
FilExt.com note: Do not attempt manual editing. Use dedicated recovery utilities when working with these files.

Windows Backup Utility
See the previous paragraphs to learn more about the main application. COPY0 files are often referred to as Windows Backup Utility backups because this type of file is primarily created or used by this software.
Microsoft Windows
*.COPY0 files are backup files primarily associated with the Windows operating system. They represent copies of the Master File Table (MFT), a crucial component of the NTFS file system. The MFT acts as a sort of index or database, containing entries for each file and directory on the volume. Each entry stores essential information, including file size, creation and modification timestamps, and security permissions. *.COPY0 files serve as a redundant copy of the MFT, providing a means of recovery in case the primary MFT becomes corrupted or damaged. This redundancy enhances data resilience and allows for potential restoration of the file system structure and data. While *.COPY0 files are typically hidden system files, their presence is vital for maintaining the integrity and recoverability of NTFS volumes. This file format is classified as System Files.
