Zone filing
The division of drives into zones enables the logical separation of the data into performance critical and non-critical
files. A special algorithm makes sure that the data on the disk is optimally organized after defragmentation. Files are
organized and moved into zones depending on their intended use and access rate. For instance, system and program
files, which need to be accessed very quickly, are separated from other data like documents and downloads.
By the division of files according to their write frequency, it is possible to intelligently prevent fragmentation. Thanks to
this logical grouping, program and system start times are shortened, future defragmentation runs faster, and new frag-
mentation can be prevented.
The system drive is divided into 3 zones by default. The zone filing proposed by O&O Defrag is optimal for the majority
of users. You may adapt this functionality to your needs by clicking Configure zones in the Ribbon bar (see User-
defined zone filing).
The following rules are set by default for the system drive:
1. Zone
Windows system files and installed applications
2. Zone:
user data, e.g. Office documents, temporary files, user profile
3. Zone:
Seldom used data and very large files, e.g. Windows Recycle Bin and files over 500 MB
Note: Zone filing is disabled by default.
