Right-click a new file in Windows and see which program created it.
Windows doesn't keep a record of which program created a file. CapyWatcher runs in the background and records every new file in the folders you choose: the program that created it, the program that started that one, the user and the time. When a file turns up and you wonder where it came from, the answer is already there.
It's made for people who run AI coding agents such as Claude Code, Codex or Cursor, for Windows power users with mystery files, and for anyone who wants to know which installer, game, download or script put a file on their computer.
WHO CREATED THIS FILE
Right-click one new file or several in a tracked folder and select "CapyWatcher: who created this file?". Each file gets its own answer: the program that created it, the program that started that one, its folder, the user and the time. You can also look up a file from inside the app, or drop files and folders on its window.
AI AGENTS
A file written by node.exe or cargo.exe also names the program that started it, such as claude.exe. So you can see what your AI agent wrote and where. Like git blame, for new files.
HISTORY
Start from a program and see every file it created. Search by path, program and user, filter by program, parent process, user and time, and export what History shows to CSV. Hide a process that creates files all day, and History leaves it out.
DELETE ALERTS AND FOLDER LOCKS
Turn on a tracked folder's bell, and a Windows notification says which program deleted files and how many, with a button to stop it. Lock a folder, and nothing can delete, move or rename its files until you unlock it. A program running as administrator can remove the lock, and CapyWatcher puts it back within 2 seconds and tells you.
WHAT'S USING THIS FILE
Right-click a file or folder to see each program using it, with its icon, name and user. Close a program from there, or stop it if it doesn't close.
IN THE EXPLORER MENU
Right-click a file, folder or drive for the CapyWatcher submenu: show it in History, track or stop tracking it, lock or unlock a folder and turn its delete alerts on or off. On Windows 11 it's under Show more options.
ANY DRIVE, USB AND NETWORK DRIVES TOO
Track folders on any drive in your computer, on a USB drive or pendrive, or on a network drive or share you add. On a network drive, CapyWatcher records what programs on your computer do there, and offers delete alerts but no lock. When someone on another computer creates, renames or deletes a file in a folder you share, History shows their address and name.
FILES PER FOLDER
See how many files were created and deleted in each tracked folder: today, over 7 or 30 days, or since tracking began.
RENAMES KEEP THEIR RECORD
A download renamed when it finishes still names the browser that saved it.
