# Which disk cleanup software removes lingering app files and junk folders after uninstalling applications?

Hi G2 community! I am researching Disk Cleanup tools for post-uninstall residue cleanup, specifically the files, folders, and registry entries that survive after the main application is removed and silently accumulate storage and registry clutter over time.

CCleaner: The Uninstaller tool shows installed applications with last-used dates, publisher, size, and install date, letting users identify what hasn't been opened in months and remove it completely, including associated registry entries. The registry cleaner targets obsolete software paths, missing shared DLLs, and invalid application entries left after removal.
CleanMyMac: Post-uninstall residue cleanup on Mac is specifically the use case multiple users name as the reason they keep CleanMyMac installed. The Uninstaller tool is the primary reason to keep the subscription, removing associated files and folders that survive a standard drag-to-trash uninstall.
Cleanmasterofficial: Handles junk folder cleanup and general residue clearing. Reviewer evidence for post-uninstall residue detection specifically, where the tool identifies and removes files associated with previously removed applications. Provides general cleanup value, but the specific post-uninstall use case is not validated as a primary strength.
Treesize: Can surface large orphaned folders left by uninstalled applications through its disk analysis view. However, Treesize does not identify files as post-uninstall residue automatically; it shows you folder sizes and lets you investigate, but it cannot distinguish a legitimate application folder from an orphaned one. Acts as a manual discovery layer rather than an automated residue cleaner.

For users whose primary cleanup motivation is post-uninstall residue, how much storage have you recovered from files left behind by removed applications, and did you find the residue through a dedicated uninstaller tool or by noticing unexplained storage consumption?

It can show you a large folder, but by then you've usually forgotten which app it belonged to or whether it was actually uninstalled versus just unused. CCleaner and CleanMyMac both solve that by tying cleanup to the uninstall event itself, so the tool already knows what was just removed rather than asking you to recognize orphaned folders later from a size list. Cleanmasterofficial does general junk clearing without either mechanism. For anyone who has actually recovered meaningful space this way, did it come from catching residue right at uninstall time, or from later discovering an old orphaned folder you'd forgotten about?</p> ##### Comment Metadata - Posted at: 17 days ago - Author title: SEO Content Writer ## Related discussions - [How well does Trello scale into a larger team?](https://www.g2.com/discussions/1-how-well-does-trello-scale-into-a-larger-team) - Posted at: over 13 years ago - Comments: 6 - [Can we please add a new section](https://www.g2.com/discussions/2-can-we-please-add-a-new-section) - Posted at: over 13 years ago - Comments: 0 - [Quantifiable benefits from implementing your CRM](https://www.g2.com/discussions/quantifiable-benefits-from-implementing-your-crm) - Posted at: over 13 years ago - Comments: 4
