DiskBrain is a Windows disk-space analyzer for people who want to see which folders occupy local storage and track how that use changes. It scans local drives and presents directory usage as a visual tree, with directory-level AI explanations intended to help identify large folders, temporary files, caches, and app leftovers. The no-installer executable is for Windows 10 and 11, making this a focused desktop option for solo users and small setups rather than a cross-platform storage console.

Its combination of scan history and cleanup tools is central to the product. Automatic snapshots let users compare scans and follow storage changes over time; Pro adds timeline trend charts and report export. File copy, delete, and rename operations are included in the Free plan, alongside fast scanning, the visual tree, and one C-drive cleanup per month. Directory Advisor helps identify junk and leftovers, while AI analysis offers explanations at the directory level. This emphasis suits users who want context for what is taking space, not only a ranked list of large files.

The Free plan costs nothing and provides the basic scan, snapshot, comparison, file operations, and monthly C-drive cleanup. Pro Monthly costs $3.99 per month; Pro Yearly costs $23.99 per year. Both provide 100 AI analysis calls per day, 50 snapshots, timeline charts, report export, unlimited C-drive cleanup, and a license for two devices. Lifetime costs $99 once and includes full Pro features, future updates, and a perpetual license. According to the listed terms, first-time monthly or annual subscribers have a 48-hour refund window, while Lifetime purchases have 7 days. Choose DiskBrain if Windows-based visual discovery and tracked cleanup fit your routine; look elsewhere if you need a different platform.
