When a file is saved, it is stored on a physical storage device such as a hard drive or solid-state drive. The data is saved to specific blocks on the storage device, which are accessed using a file system. The file system manages the allocation of storage space and keeps track of the locations of the saved files. The location where a file is stored depends on the operating system and the user's preferences. In modern operating systems, files can be stored on the local hard drive or in the cloud, such as with cloud storage services like Dropbox or Google Drive. Furthermore, some applications might have their own specific storage locations.
