ESP32 Cleaner
Deep-cleans your SD card without you ever pulling it out of the slot. It finds the hidden junk that Macs, PCs, phones and NAS drives leave behind and removes it on the device.
Plug an SD card into a Mac, and it populates every folder with .DS_Store files and adds a hidden twin next to every file. Windows, Linux, Android, and NAS drives leave their own clutter, too. While your computer hides these files, a handheld's file browser shows them all, making your file lists messy. Cleaning them usually means finding a computer and knowing exactly which files are safe to delete.
ESP32 Cleaner does it right on the device. It scans the card and groups the junk by where it came from. You can clean a whole group at once or pick individual files—anything you don't select stays safe. "Quick Clean" scans and removes in one step, while "Dry Run" shows you what would be deleted without actually touching anything. You can even add your own rules on the device or via a text file on the card.
Risky rules, like empty folders and log files, are off by default and require a double confirmation before they are deleted. It can handle cards with tens of thousands of files and works on both the Cardputer and Cardputer ADV.
