xCoreDisk Application

xCoreDisk Application (Rel. 2)

  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, 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.

- 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 disc, the application allows you to put the disc in a different location. For this click on the arrow next to the word "Advanced": the creation dialog will be modified as in the following image.

    Deactivating the "Default" flag will allow you 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 "NewDisk" and will be placed in C:\temp\.

    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 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 FAT family of filesystems (FAT12/16/32). It has similar design though renders 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

Disk backup

    This command allows you to backup the disk to a file; selecting this menu will bring up a dialog box in which you will be asked for the backup file name and its location.

    The backup operation has the following characteristics and limitations:

  • this command backsup only the disk present in the default position; any other disc created in another location will not be taken into consideration and the user must be careful to regularly create an emergency copy of the disk data
  • the application backsup the data in encrypted form: it will not be necessary to take particular measures to protect the contents of the backup file
    NOTE - The xCoreDisk.exe application backs up all the files inside the "xcoredisk" folder located in the default location. Because these files represent the space actually occupied in the virtual disk, the size of the final backup file will depend on the disk space occupied and not on the global dimensions.

Disk restore

    With this command it is possible to restore the backup of a previously saved disk. Note that the operation will restore the backup file data to the disk located in the default location.

      Disk restore
    The restore operation does not work if in the default position already exists a disk (ie a folder) with the name "xcoredisk".
     The program does not allow overwriting, so it will be necessary to manually delete the "xcoredisk" folder with all its contents.

 - The default folder is "C:\Users\%USERNAME%\AppData", where %USERNAME% represents the name of the user (account) currently logged in to Windows.
    This is a hidden folder: to view it you will need to enable the display of hidden elements in Windows Explorer:

Service disk

    All devices allow to see, when inserted into a USB port, a read-only disk of small size (1 MBytes) with the name "XCDAPP" which contains the XCoreDisk.exe application and some accessory files. This disk is indicated below with the name of Service disk.

    The usefulness of this disk is evident above all in the case of first use and in all cases in which you want to access a disk on a PC on which the XCoreDisk.exe application is not present..

     Clicking on the menu "Service Disk" opens an additional menu that allows you to disable or enable the Service disk: it can be superfluous (and sometimes annoying) the fact that a disk drive appears every time the device is inserted in a USB port.


    By choosing this option it will be possible to deactivate or reactivate the Service disk.

     The next time the device is inserted into a USB port, the Service disk will appear or it will not appear depending on the option set.

Create service disk image

    The application allows you to create an image of a disk of fixed size (1 MBytes) that can then be loaded on the service disk. This allows you to customize the contents of this disk so that you can put whatever you want.

     By clicking on this menu the following window will appear:

    Click on "Browse" and choose the name of the image you want to create; then click on "Create".

     NOTE - If an already existing image is selected, the "Create" button becomes "Open" and it will be possible to manage a previously created image.

     At this point, in Windows Explorer you will see a new disk of the size of 1 MByte that will have to be formatted and in which you can then copy the files you want to have in the service disk.

     At the end of the operation deactivate the disk by selecting "Disable service disk" from the main menu.

    You can then load the image you just created by following the instructions in the next paragraph.

Upload image

    The Service disk contains the XCoreDisk.exe application in the version released at the time of production of the device. This application, however, is constantly evolving and, for this reason, it has been provided not only that it can be downloaded from OxySec sites, but that it can also be stored on the device by replacing the existing one and now outdated..

    By clicking on the "Upload image" menu the following window will appear.

    Click on "Browse...", choose the image file to upload and click on the "OK" button: a window will appear that warns you that the operation may take some time.

    At the end, the result of the operation will be indicated.
