O&O Defrag guarantees you complete data integrity and security. Only functions that are implemented in Windows by the operating system itself are used for defragmentation and synchronization of all file accesses.
File attributes (Date, Time, System, Archive etc.) and the security settings for NTFS drives will not be changed. Access rights also remain unchanged. In addition, only one file per drive will be processed at any one time. This ensures that even in a worst case scenario, only one file will be lost (e.g. if there is a power cut). If you have more questions concerning data security, we can provide you with more information. Do not hesitate to contact us at: firstname.lastname@example.org
