What Is File Compression In NTFS System?

Files on the NTFS quantity have one quite useful quality - "compressed". NTFS has built - in hold up of disk density. Previous Stacker or DoubleSpace was used for this reason. Any file or index in the individual arrange can be stored on the disk in the dense form and this process is totally clear for applications.

The file compression has very much elevated speed and only one large unenthusiastic property - huge virtual breakup of compressed files which however does not bother anyone. The density is approved by blocks of 16 clusters and uses supposed "virtual clusters ". This choice is tremendously supple and permits to attain interesting effects - for instance a half of file can be dense and a half is not. It is achieved because the in order storage about solidity rate of the defined fragments is very alike to usual file breakup.

It is able to be seen that the compressed file has "virtual" clusters which don't contain the genuine information. As soon as the scheme sees such practical clusters, it realizes at one time that the data of the earlier block multiple to16 should be decompressed and the data immediately will fill in virtual clusters and this is the entire algorithms.
