How is the placement of files in RAM carried out after copying them from the hard drive?

When a file is copied from a hard disk to RAM, the operating system allocates blocks of memory for it, which do not necessarily have to be contiguous physically.

In RAM, data is stored in pages or blocks, and the OS manages their placement through the virtual memory mechanism. This means that the file is divided into parts, each of which is loaded into free memory pages.

Thus, the arrangement in RAM can be fragmented, but access to the file by programs is done through virtual addresses, which the OS maps to physical memory addresses. This ensures efficient memory usage and process protection.
