The first time my drive cornered me was a Monday morning

I opened my laptop to send a client a proposal, but the system warned me there wasn't enough space. I was in a shared office in Yuhang, Hangzhou. I spent 20 minutes searching through my Downloads folder, then deleted a batch of old assets anyway. Only later did I realize what usually takes up the most space isn't documents; it's the caches, installers, and system leftovers left behind by AI tools. More tools don't automatically mean more efficiency. They can mean we spend every day making room.

Mole does something simple: show you the clutter, then let you clear it

Mole is a cleanup tool for macOS that also supports Windows. It scans for application leftovers, system data, and AI-tool-related files, then lets you decide what to delete instead of handing your computer to a black-box button. What appealed to me wasn't the “fully automatic” part, but its slower pace: scan first, review next, confirm last. That worked for me because I don't want to wrestle with code.

I know Lin Yue, a friend who builds a personal IP brand. From her apartment in Panyu, Guangzhou, she was testing writing, video-editing, and AI image tools at the same time. In March 2025, her computer had only about 38GB of space left. After using Mole, she moved three old projects' export bundles elsewhere and cleared roughly 9GB of tool caches. She later told me, “I'm not incapable of managing my tools. I just had no idea where the junk was hiding.” That was when cleanup tools started feeling less like a neat-freak obsession and more like a way to save a small team time.

Reproducing it today: about ¥0, with the first scan taking under 30 minutes

Money: You can start with the basic version for ¥0; whether you pay depends on the features and version you need. Time: About 30 minutes, though the first scan may take longer. Technical barrier: No coding required, but you need to recognize file names and get into the habit of backing things up. First step: Open Mole, click “Scan” or “Start Scanning,” and resist the urge to delete anything yet. Send the results to your own email or cloud drive as a backup, then review each item.

I used to make the mistake of selecting everything under “System Data,” then realizing the cleanup had removed one app's history too. Now my fixed order is: back up, scan, review item by item, and clear only caches and obvious leftovers. One more thing: this doesn't mean everyone needs to buy cleanup software. If your drive still has room, or your company manages devices centrally, trying it now isn't necessary.

Here's how I'd approach it at each stage

If you're just starting out: I'd run one free scan and clear only caches and installers. I wouldn't rush into paid features or organize projects I haven't started yet.

If you already have 1-2 clients: I'd back up client assets first, then clear old versions, AI-generated files, and duplicate exports. Keeping 20 minutes aside each month feels more reliable than emergency cleanup after the drive fills up.

If you're scaling up: I'd add device cleanup to a weekly routine, but I wouldn't let everyone delete files independently. One owner should approve the retention rules, and important files should still live in the company's approved backup location. Tools can save time; permission boundaries can't be skipped.
