Task 108: .CPY File Format

The .CPY file extension is associated with multiple contexts based on available documentation, primarily as a proprietary format without publicly disclosed detailed specifications. It is most commonly linked to Autodesk 3ds Max for storing copied animation tracks, poses, and postures; to Nuance eCopy Desktop (now eCopy PaperWorks) for scanned document data similar to PDF; or to COBOL programming as text-based copybooks defining data structures. No comprehensive, reverse-engineered binary format specifications were identified in technical resources, file format archives, or developer documentation, indicating that the internal structure is not openly available for decoding or manipulation.

Properties intrinsic to the file format: Due to the proprietary nature of .CPY files in primary contexts (3ds Max and eCopy), no detailed internal properties or structures (such as headers, fields, or binary layouts) are publicly documented. For COBOL copybooks, which are plain text, properties include hierarchical data definitions (e.g., level numbers like 01 or 05, PIC clauses for field formats, and OCCURS for arrays), but these are not binary-encoded and vary by implementation. General file system properties applicable to any .CPY file include creation date, modification date, file size, permissions, and ownership, though these are not format-specific.

Direct download links for .CPY files: No verifiable direct download links to sample .CPY files were located in public repositories or archives. Searches yielded references to related tools or discussions but no accessible samples. For testing purposes, users may generate .CPY files using the originating software (e.g., Autodesk 3ds Max for animation copies or legacy eCopy Desktop for scans), or create text-based COBOL copybooks manually.

3-7. Code implementations: Without public specifications for the internal structure of proprietary .CPY files, developing accurate code for decoding, reading, writing, or displaying properties is not feasible, as it would require assumptions that could lead to errors or incompatibility. For COBOL copybooks (text-based), parsing can be achieved with standard text processing, but this does not align with the request for binary decoding. If proprietary tools or reverse engineering were pursued, it would exceed the scope of available information.
