Google Drive duplicate finder

Find exact Google Drive duplicates without downloading every file.

ClearCopies reads the metadata Google Drive already exposes, prioritizes SHA-256, SHA-1, then MD5 checksums, and groups only files with the same byte size and comparable fingerprint. You review the evidence; the scan never changes your files.

Implementation verification · August 2026

Tested against Google Drive API behavior

The integration tests read Drive quota, reconstruct nested paths, retain sharing context, and normalize the strongest available SHA-256, SHA-1, or MD5 checksum. Scans only read; files move only in a paid cleanup.

Google-native Workspace files do not always expose comparable binary evidence; the tested workflow leaves those items outside exact groups instead of inflating recoverable storage.

How it works

A Google Drive scan built around checksum evidence

Google Drive has its own mix of uploaded binaries, native Docs files, shared items and nested folders. The scan keeps those differences visible instead of forcing every item into an exact-match result.

  1. 01

    Authorize Google Drive

    Google asks once for Drive access. The scan only reads; nothing moves until you pay for a cleanup.

  2. 02

    Map files and folder paths

    The adapter enumerates non-trashed items, reconstructs their folder paths and records sizes, timestamps, sharing state and available checksums.

  3. 03

    Review defensible groups

    Uploaded files become exact candidates only when byte size and a checksum from the same algorithm agree. Unsupported items remain for manual review.

Provider-native fingerprint

Why Google checksums are stronger than matching names

Google may expose more than one checksum for an uploaded binary. ClearCopies normalizes the strongest available value into one fingerprint while retaining the algorithm name, so an MD5 value is never compared as though it were SHA-256.

  1. 1

    Drive metadata

    size + sha256Checksum / sha1Checksum / md5Checksum

  2. 2

    Normalized signal

    algorithm name + content fingerprint

  3. 3

    Exact candidate

    same byte count + same comparable fingerprint

Google-native Docs, Sheets and Slides may not expose a binary checksum or meaningful byte size. ClearCopies does not promote those items to an exact group without reliable fingerprint evidence.

Least-privilege access

What ClearCopies can see in Google Drive

Google asks once for full Drive access, so a paid cleanup needs no second sign-in. The scan only reads.

Reads for the scan

  • File identity and location

    Names, IDs, MIME types, parent folders and reconstructed paths.

  • Duplicate evidence

    Byte sizes and Google-provided SHA-256, SHA-1 or MD5 values when available.

  • Review context

    Created and modified times, sharing state, ownership hints and available thumbnail links.

Does not do

  • Download file bodies for hashing

    Exact grouping uses checksums returned with Drive metadata rather than transferring each file to ClearCopies.

  • Change files during a scan

    Nothing moves until you pay for a cleanup, and then only to Google Drive trash.

  • Call a name match an exact duplicate

    A repeated filename or byte count can create a review lead, but neither proves identical content.

Trash only after you pay

Reviewed copies move to Google Drive trash only after you pay for a cleanup. Each file is rechecked right before it moves, behind ClearCopies' server-side cleanup gate.

Google Drive FAQ

Questions about scanning Google Drive

Straight answers about fingerprints, permissions and the boundary between review and cleanup.

Does ClearCopies download my Google Drive files?

No. Duplicate grouping uses file metadata and Google-provided checksums. ClearCopies does not download every file body to calculate its own hash.

Which Google Drive checksum does ClearCopies use?

It prioritizes sha256Checksum, then sha1Checksum, then md5Checksum when Google exposes them. The algorithm travels with the value so different checksum types are never treated as interchangeable.

What happens to Google Docs, Sheets and Slides?

Google-native workspace files may not include a binary checksum or byte size. Without reliable fingerprint evidence, ClearCopies does not classify them as exact duplicates.

Can ClearCopies delete or move my Google Drive files?

Only in a cleanup you pay for, and only to Google Drive trash. The scan never changes files, and every cleanup stays gated on the server.

Can ClearCopies inspect shared Google Drive items?

The adapter includes items visible to the connected account and records Google's sharing indicator. Actual visibility still depends on that account's Drive permissions.
