Final answer:
The default installation folders that should not be manually modified or deleted are 'System32' and 'Program Files' on Windows and 'System' and 'Applications' on macOS. These directories contain essential files for system stability and application functionality.
Step-by-step explanation:
The default installation folders that contain system and application files and should not be manually deleted or modified normally are typically found in the Windows system directory for Windows operating systems, such as System32 and Program Files for both 32-bit and 64-bit applications. For macOS, this would be the System folder and Applications directory. These directories contain critical system files and application binaries that are essential for the operating system and installed programs to function properly. Modifying or deleting files in these locations can lead to system instability, application errors, or even make the system unusable.
The default installation folders that contain system and application files that should not normally be deleted or modified manually depend on the operating system being used. In Windows, for example, some of the important folders are: C:\Windows\System32: Contains critical system files and libraries. C:\Program Files: Holds the installed applications and their associated files. C:\Program Files (x86): houses the 32-bit applications on 64-bit versions of Windows. In macOS, the following folders are significant: /System: Contains the core system files. /Library: Holds system-wide resources and files for installed applications. Applications: houses the installed applications.
