Choose a folder

SpaceQuay maps the files in a selected folder and keeps a history of read-only metadata scans. Select a folder, scan it, explore the map and largest-file list, then compare two complete scans to see path changes.

SpaceQuay reads names, paths, file types, sizes and timestamps, without reading file contents. It does not follow symbolic links or cross into nested mount points. Cloud-only directory traversal is skipped, and cloud file contents are not downloaded. Hidden items and package traversal follow the displayed policy.

Scans can stop at 1,000,000 encountered entries or 128 directory levels. Cancellation, access failures and limits mark an audit incomplete. Incomplete scans are saved separately and never replace the last complete scan. Scanning a changing folder is not an atomic filesystem snapshot.

Understand both size measures.

Logical size is the sum of regular file sizes by path. Hard-link paths each contribute logical bytes. Allocated file blocks count an identity once within a scan. APFS clones, sparse files, compression and shared blocks prevent these totals from being a measure of reclaimable space. Directory and filesystem overhead, purgeable data and snapshots are not fully measured.

Extension groups are based on file names. File content is not inspected.

Age uses the recorded modification time, not the last time a file was opened.

Change ledger

Comparison requires two complete scans of the same folder identity and policy. The ledger identifies added, removed, larger, smaller or timestamp-changed paths. Renames and moves appear as removed and added paths. It cannot detect same-sized content changes or certify a backup.

The ledger compares logical sizes and metadata, not file contents. Same-sized content changes may be invisible. Negative bytes do not prove disk space was recovered.

Export audit report

Export a portable JSON, spreadsheet-friendly CSV and self-contained searchable HTML audit to a unique new folder. Existing files are not overwritten. Partial output is kept after an error. Reports include relative paths and folder labels, so review them before sharing.

The HTML audit displays up to 5,000 rows for responsive browsing. CSV and JSON retain all recorded rows. The HTML clearly shows any remaining row count.

Reports include folder labels, file names and relative paths. Review them before sharing.

A SpaceQuay scan JSON can be opened as a historical audit. Import is limited to 512 MiB, 1,000,000 records and 64 KiB per record line. Unsupported schemas, unsafe paths, duplicate rows or inconsistent totals are rejected. Importing does not grant live access to the recorded folder.

Restore purchases

The sample audit and saved scans are free to browse. Activate a 7-day Trial through Apple for 168 hours of live folder scans and new report exports, or buy permanent access. The trial does not automatically charge you. Existing audits and exported reports remain available after it ends.

Prices and payments are supplied by the App Store. Purchasing and restoring may require an internet connection. File analysis stays on this Mac.

Saved audits stay available after the trial ends. They are historical records, not a live view of the folder.

Exclusions & access issues

This is selected-folder storage analysis. It does not delete, clean, move or rename source files. It does not promise a full System Data inventory, exact recoverable capacity, APFS clone accounting, backup verification or disk health diagnosis. Modified time is not last-used time.

Intentional exclusions are different from access failures. Review both when comparing results.
