LumaDisk vs SizeTrend

LumaDisk is a disk space analyzer for macOS and Windows that maps a filesystem to show what is using storage. Its interactive sunburst and treemap views update during a scan. The app groups regenerable developer folders such as node_modules, /target,.next, and DerivedData, and groups duplicate files with one copy selected to keep. It also lists files of at least 100 MB that have not been opened for six months, a year, or two years. External drives are fully supported; network volumes can be analyzed read-only. Cloud support includes iCloud Drive, OneDrive, and Dropbox, while Google Drive is described as coming soon. The free plan keeps scanning and the sunburst view available. A LumaDisk license is listed at $6.89 a month, billed as a one-time payment rather than a subscription, and covers up to five Macs. Requirements are macOS 12 or later on Apple Silicon, or Windows 10 or later on x86-64 or ARM64. Reclaim permanently deletes files, with a ten-second undo window and safeguards against queuing system folders.

SizeTrend is a Windows application for examining disk use across files, folders, and applications. Its scans show application sizes and file-type breakdowns, analyze file contents, and identify duplicates. Search can filter by name, text, binary content, type, size, or date; duplicate detection compares names, sizes, or content. The free edition includes local disk analysis, saved snapshots, and one What Changed comparison when a compatible snapshot exists. A single-file portable download is available, and files or folders can be compressed in place. Professional adds network-folder scans, scheduled scans, automatic storage history, unlimited snapshot comparisons, and exports to HTML, Excel, or CSV. Scans can be scheduled once or run daily, weekly, or monthly through Windows Task Scheduler. Logged-off scheduled tasks cannot access EFS-encrypted files. SizeTrend Professional costs $69.99, paid once, with no subscription and future versions included. Volume pricing is available from five licenses, including per-license rates for larger orders and an unlimited single-site option.
