What is difference between logical file and physical file?
* Physical file (PF) contains the data and have only one record format. Logical file (LF) is a view of the physical file which does not contain any data may be based on one physical file or more then one physical file. Logical file can have more then one record format. Logical can be non join or join logical file. Performance becomes better if you use the logical file in the program.
What is logical file?
Logical file is a type of file that provides a view of the data stored into the Physical file. It does not contain data. A logical file contains only an index to the data stored into the physical file.

How do you convert RPG prtf to pf?
To convert an RPG program (PRTF) to a physical file (PF) in IBM i, you can use the CRTPF (Create Physical File) command to create a physical file that matches the structure of the RPG program. You would typically define the fields in the PF based on the data definitions used in the RPG program. Once the PF is created, you can then modify the RPG program to read from or write to this physical file instead of using a print file. Make sure to adjust the program logic as needed to handle the data correctly.
What is a physical file organization?
Physical file organization refers to the way data is stored on a physical medium, such as a hard drive or SSD. It involves the arrangement of records in a specific format, such as sequential, heap, or indexed, to optimize data retrieval and storage efficiency. This organization impacts how quickly and effectively data can be accessed, updated, and managed within a database or file system. Proper physical file organization is crucial for performance, especially in systems with large volumes of data.
What is better a computer or a file system and why?
A file system is necessary for a computer to work with files; however, a file system is not a physical object, and is pretty useless without a computer to use it on.

What is the minimum size of the paging file required to allow a memory dump in the event of a stop error?
That depends on how much memory is being used by the operating system, the apps and their data. In general a paging file is 2 to 3 times physical memory so, 4x the physical memory (paging file of 3x physical memory + physical memory) will guarantee enough room for all data IF the paging file is set to 3x physical memory. There would be more needed for the devices attached to the processor, but there will be holes in memory and these holes most often more than make up for the memory of attached devices.
