Upon installation, a program typically places itself in the Program Files directory, based on its architecture (32-bit or 64-bit). If it's a standalone app, it remains in the original file location unless otherwise relocated.
When you save an app, you usually receive a downloadable setup file (like .exe or .msi). This is comparable to a .dmg file on macOS. There isn’t a direct match for simply dragging the file into an app folder, as is common on macOS. Instead, you must double-click the installer to launch it, which then installs the actual program. Generally, it goes to a location such as C:\Program Files or C:\Program Files (x86), based on whether the app is 64-bit or 32-bit. If the file appears to have been moved, it could be flagged by a virus scanner and placed in quarantine. Usually, an app comes packaged as an installer rather than a standalone file.
Tip: When dealing with multiple drives, avoid putting programs on your main OS drive unless absolutely necessary. This way, if you need to reinstall Windows or restore data, you'll retain most of your files on the other drives. Remember to back up your OS drive regularly, since reinstalling can erase important files like game saves and appdata.
