xCoreDisk Application ‎‎(Rel. 4)‎‎


  Disk menu

    Clicking on the "Disk" menu will open the submenu shown below.


Create disk

    The "Create disk" command allows you to create a new encrypted disk. By clicking on this menu the window shown below will appear.



     To create a disk in the default position and with standard parameters for CronoDisk exstension, simply enter the size of the disk, the device password and then click on the "OK"  button. If a disk already exists in the default location, the application will return an error indicating that it will first be necessary to manually delete the disk (that is the folder) already present.


      Default disk location
    By default, the disk is created with the name "xcoredisk" in the following folder:
  • C:\Users\%USERNAME%\AppData\Local\OxySec\
  where %USERNAME% represents the name of the user (account) currently logged.

     If you want to remove this disk, it will be sufficient to delete the "xcoredisk" folder with all its contents.

    NOTA - The folder "C:\Users\%USERNAME%\AppData" is a hidden folder: to display it you will need to enable the display of hidden elements in Windows Explorer:


    When creating the disk, the application allows you to put the folder that represents the disk in a different location. To do this, uncheck "Default" in the Advanced part: it will be possible to choose a name for the folder that represents the disk as well as the destination in which to place it. In the following window, for example, the folder that will contain the encrypted data is called "MyDisk" and will be positioned in C:\.



    You can also select a different size for data storage blocks. Changing this value can be useful if the disk is created in an area that is synchronized to the cloud: in this case, it may be useful to calibrate the size of the blocks to optimize the band used by the synchronization service.


   Disk formatting

    For the choice of the filesystem to use, it is important to take into account the fact that the newly created disk is a removable disk.

    For this reason, we recommend using the exFAT filesystem, expressly designed for removable devices such as keys and/or external disks.

    Extended File System (exFAT) is a successor of the FAT family of filesystems (FAT12/16/32). It has a similar design though offers many significant improvements:

  • Larger volume and file size limits
  • Native UNICODE file names
  • Bigger boot area allowing a larger boot code
  • Better performance
  • Time zone offset support
  • OEM parameters support



   Use of NTFS

    NTFS is a file system that uses very advanced features. Among the most important we remember the possibility of assigning permissions to files and folders, a register that keeps track of the changes applied (NTFS is journaled), a system that involves the use of shadow copies, support for encryption, for the hard link, for long names (the name of files and folders can occupy up to 255 characters and contain characters of any language thanks to the use of Unicode encoding) and much more.

    However, some of these features can be counterproductive if used for removable disks such as, for example, virtual disks created by xCoreDisk.

  • Being journaled, there will always be a read/write activity of the operating system, regardless of the user's actions; combined with the fact that the operating system itself caches (that is to say that you have written everything while it has not actually done so) it is clear that the unsafe removal of the disk, specifically the unsafe removal of the xCoreDisk virtual disk, can cause data loss if not the entire disk. For this reason it is absolutely essential to properly remove the virtual disk before removing the xCoreDisk device.
  • By managing the access authorizations for each individual file, disconnecting and reconnecting the disk represented by a folder placed on the network could be problematic as the host operating system could already consider the files that represent it and therefore prevent access when try to replace the virtual disk.


    The last part of the disk creation dialog concerns the configuration of the CronoDisk extension which allows you to automatically create disk recovery points so that you can have a history of the disk content.



    In the image, for example, it has been chosen to have a maximum of 20 restore points created every 1 day at about 10:30 pm.

Restore points: CronoDisk

    This menu item, selectable only if the CronoDisk function is active, allows you to manage the recovery points created. View the specific page of the manual: CronoDisk: restore points for more details.
