Google Docs duplicate files occur when multiple copies of the same document unintentionally exist in your Google Drive storage. This often happens during manual creation of copies ("Make a copy" option), syncing errors with desktop Drive apps, accidental multiple uploads, or conflicting edits triggering new copies. Unlike file versions, which track revisions under a single file, duplicates are separate files consuming space and potentially causing confusion. Resolution focuses on identifying and removing extras while preserving the intended file.

For example, users frequently create duplicates when uploading a local file already in Drive, or by selecting "Make a copy" within a shared folder instead of moving the original. Businesses may face this when teams collaborate on proposals, leading to multiple parallel "final_v2" files scattered across shared drives. To resolve, use Google Drive search operators like is:duplicate to find suspected duplicates, visually inspect filename lists in folders you use frequently, and utilize Docs' "Version history" (File > Version history > See version history) to revert major accidental changes rather than keeping copies.

While duplicate creation offers a safety net against accidental edits, unchecked proliferation wastes storage and causes version control issues. Key advantages include simple recovery options; limitations involve manual identification overhead and lack of true automatic deduplication. Ethically, ensure you have rights before deleting shared files. Future improvements may see smarter Drive-level duplicate management features. Regular cleanup improves efficiency.
