A memory-mapped file contains the contents of a file in digital memory. This mapping between a file and memory area allows an software, including multiple processes, to modify the file by studying and Memory Wave clarity support writing on to the memory. You can use managed code to entry memory-mapped recordsdata in the identical way that native Home windows capabilities access memory-mapped information, as described in Managing Memory-Mapped Recordsdata. Persisted information are memory-mapped recordsdata that are related to a source file on a disk. When the last process has finished working with the file, the information is saved to the supply file on the disk. These memory-mapped files are suitable for working with extremely massive source information. Non-persisted files are memory-mapped recordsdata that are not related to a file on a disk. When the last process has finished working with the file, the info is misplaced and the file is reclaimed by rubbish collection. These information are suitable for creating shared memory for inter-process communications (IPC).

Memory-mapped files could be shared across multiple processes. Processes can map to the same memory-mapped file through the use of a common identify that's assigned by the method that created the file. To work with a memory-mapped file, you should create a view of the complete memory-mapped file or a part of it. You may as well create multiple views to the identical a part of the memory-mapped file, thereby creating concurrent memory. For two views to stay concurrent, they must be created from the identical Memory Wave clarity support-mapped file. A number of views might also be vital if the file is higher than the dimensions of the application's logical memory space out there for memory mapping (2 GB on a 32-bit laptop). There are two varieties of views: stream entry view and random access view. Use stream entry views for sequential access to a file
