Memory-mapped files can be either Persisted : written to disk at regular intervals -- for large file operations , Avoid in memory loss @ crashes Nonpersisted. : in memory throughout the life --for short-duration operations. - GC will clean
These are managed file access - Not any pInvokes -- No explicit dispose!!
Two types of views stream access view -- for sequential access to processes in interprocess communication for non persisted files random access view. -- Random access views are recommended in persisted access.
The maximum size of memory-mapped view can be 2GB on 32-bit machines and 264 GB on 64-bit machines.
Notice these capacities are same as managed heap capacities of respective machines(but no one to garbage collect. Developer need to manage)
