File extension rem information

Files with extension REM are associated with the application Delphi Memory Swap File developed by Borland. Files with extension REM are temporary files used by this file type and usually erased once Delphi closes. A swap file may also be referred to as a swap space or a pagefile in Windows NT. It is basically a space on a hard disk applied as an extension virtual memory on the computer’s real memory. Swap files permit the operating system of the computer to pretend to possess more RAM than is actually available.
RAM files that have been recently used are swapped out to the hard disk till a later time when they are needed to allow swapping in of new files to RAM. When dealing with operating systems that are larger, the moved items are referred to as pages while the swapping process is termed paging. One major advantage of swap files is its flexibility of being organized as a singular contiguous space which ensures a requirement of fewer input and output operations which are required to write or read as complete files.
