What About A Semi-Permanent Paging File?
Although everyone knows about dynamic and permanent paging files, there is a third type of paging file - a semi-permanent paging file.
A semi-permanent paging file theoretically allows you to receive the performance benefits of a contiguous permanent paging file without its main disadvantage - the need to predetermine an optimal size. But what is a semi-permanent paging file?
Well, a semi-permanent paging file is a combination of a permanent paging file and a dynamic paging file. It consists of a permanent part and a dynamic part. The permanent part of this paging file behaves exactly like a permanent paging file. It will not change in size and can thus be moved to the outer tracks of the hard disk.
The dynamic part, however, does not normally appear. In fact, it is only created when the permanent part of the semi-permanent paging file is unable to cope with increased memory requirements.
Once created, it dynamically resizes itself to suit the current paging file requirements. Just like the dynamic paging file, it will use any free space on the hard disk so it will be fragmented.
