- Automatic duplicate discovery: identify large files with the same complete filename and logical size, rank groups by potentially reclaimable space, and show every location in the Overview. SizeTrend clearly identifies these as metadata matches rather than content-verified duplicates, avoids counting hard links as separate physical copies, and verifies the selected files before deletion.
- Developer, package, and virtualized-storage cleanup: add owning-tool cleanup or review guidance for NuGet, pip, Go, Conda, Scoop, Chocolatey, Docker images, stopped containers, Docker build cache, WSL 2 virtual disks, and generated Unity, Unreal Engine, and Godot project data. Downloaded Windows Update content is also identified for review without deleting update metadata directly.
- Broader application-managed storage guidance: measure related data for Claude, Firefox, VS Code and VS Code Insiders, Slack, Postman, Zoom, Antigravity, Qoder, Cursor, Node.js and npm, and Python. Narrow disposable caches remain separate from persistent workspaces, runtimes, packages, indexes, logs, conversations, and other data that should only be reviewed, with every measured location available for inspection.
- Overview search and navigation: use the new Search button to find retained Overview suggestions by name, description, or path; narrow aggregate results to the matching locations; and collapse sections while searching. Paths can also be opened in Windows Explorer or copied from the right-click menu, navigable rows are underlined on hover, and hints show all relevant locations.
- Remembered Overview layout: preserve which Overview sections the user expands or collapses between scans and application sessions, while keeping temporary search-result expansion and collapse choices separate from the normal layout.
- Drive-capacity meter: see the current drive's used percentage and exact free space directly in the status bar, with consistent warning colors when free space falls below 10 percent and critical colors below 5 percent.
- More accurate NTFS space accounting: correctly measure compressed, sparse, preallocated, hard-linked, extended-length, and complex NTFS files; count shared hard-link allocation only once while retaining every visible path; handle allocation metadata stored in MFT extension records; and preserve useful corruption diagnostics.
- Safer saved scans and scheduled reports: publish manually saved scans atomically so an interrupted write cannot replace a valid scan with a partial file, stabilize saved-scan serialization, add Save Scan directly to the Overview header, and provide an Open Folder shortcut for scheduled reports.
- More meaningful What Changed results: report actual logical or allocated disk-space changes instead of timestamp-only rewrites, avoid reporting shared hard-link allocation more than once, and improve Explorer navigation by opening folders directly while selecting individual files.
- Safer ZIP and NTFS compression operations: track background operations through scan refresh and shutdown, work from verified file handles, handle files changed since the scan, avoid including the destination ZIP inside itself, support large ZIP statistics, fall back to the Desktop when necessary, and apply folder compression to the selected folder itself as well as its existing contents.
- Interface and workflow reliability: improve dark-mode readability across the Overview, registration, scheduling, saved-scan, and file-list interfaces; correct compact ribbon icons; disable file actions when nothing is selected; clarify scan and cleanup refresh progress; and handle stale Explorer targets without exposing raw shell errors.
- Scheduled scans and automatic history: create and manage one-time, daily, weekly, or monthly scans through Windows Task Scheduler; run them while logged off without storing a password; configure elevation, power, wake, missed-start, and retention behavior; review their status and results; and store later snapshots as compact deltas when that saves space, with an automatic full-scan fallback when necessary.
- Reports and data export: save the Overview as a self-contained HTML report; export the file tree, largest, newest, modified, or duplicate-file results to Excel or CSV; and configure a scheduled scan to generate the selected report automatically after each complete scan.
- Faster and safer saved-scan management: a local artifact catalog lists large scan collections without reopening every file, distinguishes manual scans, automatic snapshots, scheduled and partial results, full scans, and dependent deltas, protects required base scans, prevents path-hash collisions from matching the wrong file, and highlights unusually large scan history for review.
- SQL Server storage diagnostics: identify MDF, NDF, and LDF files under registered local SQL Server storage locations, grouped by instance where possible, without connecting to SQL Server or implying that database files can be deleted directly.
- IIS storage review: read the effective IIS configuration, identify access and failed-request log locations, review older logs by age, and show the physical folders used by sites, applications, and virtual directories—including deployments outside inetpub—without double-counting shared content.
- Stale print-job review: find large older jobs still held in local Windows print queues, show the document, printer, owner, submission time, state, and size, and ask Windows to cancel only the jobs selected by the user. SizeTrend never deletes spool files directly.
- VMware storage review: recognize virtual-machine folders and their disks, snapshots, suspended-memory files, and configuration files; separately flag large VMDK files that may be orphaned; and direct the user to verify ownership in VMware.
- Developer build-artifact discovery: use Cargo, Visual Studio, Delphi, and recent VS Code project metadata to find generated Rust, Node, Python, Java, CMake, executable, package, library, DCU, bin, obj, and other intermediate output, grouped by project with shared output counted once.
- AI coding-tool storage guidance: add Kiro and Cursor storage analysis alongside the existing Codex and Claude cleanup guidance, distinguishing rebuildable caches from conversations, sessions, settings, extensions, logs, steering data, execution history, and agent worktrees that should be preserved or reviewed separately.
- Broader cache and application-storage guidance: distinguish persistent Firefox, Chrome, and Edge site data from ordinary browser cache; clean only verified Discord and Spotify caches while preserving offline downloads; include Windows SystemTemp; and improve shared-folder accounting for installed applications, Comet data, and Outlook PST and OST locations.
- More Windows-native operation: follow the Windows light or dark application setting throughout the interface, accept typed or pasted scan paths directly from the status bar, show Low and Critical free-space states, and remember the user's administrator-startup choice while retaining the non-elevated fallback scanner.
- Faster, clearer analysis: run Overview producers independently, publish completed sections as soon as they are ready, cache project metadata, expand aggregate recommendations into their individual locations, start file-search progress immediately, and keep What Changed results independent and consistently sorted.
- Safer deletion: show the selected paths in Recycle Bin and permanent-delete confirmations, compact very long paths, use the scanned tree to prepare large deletions, detect descendants created during deletion, and name applications that Windows reports as holding remaining files open.
- Reliability improvements: avoid stack overflow on unusually deep NTFS hierarchies, tolerate inaccessible directory monitors, improve saved-scan collision and partial-result diagnostics, and make scan-progress completion and contrast more consistent.
- New drive type support: In addition to NTFS, SizeTrend now supports lightning-fast direct scans of FAT32 and exFAT volumes, including removable drives. It also supports BitLocker-protected volumes.
- Much faster file-content search: Searching inside files can now run up to 20 times faster while retaining case-insensitive ASCII, UTF-8, and Unicode matching.
