Instead of copying the file, create a symbolic link inside your Google Drive folder that points to the real halo.exe .
Here is how I set up a dead-simple, cloud-backed version control system for halo.exe using only and a batch script.
If halo.exe must run from a specific folder, use a Google Drive shortcut and a launcher script:
xcopy "%USERPROFILE%\Documents\My Games\Halo MCC" "C:\Google Drive\Halo Backups\Saves" /E /I /Y xcopy "C:\Program Files (x86)\Steam\steamapps\common\Halo The Master Chief Collection\config" "C:\Google Drive\Halo Backups\Config" /E /I /Y Schedule it via Task Scheduler to run every time halo.exe closes.
Right-click halo.exe in your Drive web UI → Manage versions . Every time halo.exe updates locally, Drive saves the old version. Roll back in 2 clicks.
We all have that one critical executable or tool—let’s call it halo.exe —that we cannot afford to lose. Whether it's a proprietary internal tool, a compiled script, or a legacy game mod manager, losing it means hours of rework.
