About File Export
When exporting files by using the File Export utility, ensure that the drive (the system disk) storing the system temporary files must have the available capacity described in the following table.
Export Destination Drive | When original file is not original file backup | When backing up original file (Note 1) | |
|---|---|---|---|
DVD/CD | More than 1.5 times of the capacity of files that are actually exported | More than 2.5 times of the capacity of files that are actually exported | |
Except DVD/CD | When it is not system drive (Note 2) | Not required | Same capacity as that of files that are actually exported |
When it is system drive | Same capacity as that of files that are actually exported | More than 2 times of the capacity of files that are actually exported | |
Note 1: When backing up the original file, the log folder of the client (CT) must have the capacity that is equivalent to the size of the original file in addition to the capacity described in the above table.
Note 2: Specify the drive that satisfies all the following conditions:
Except DVD/CD drive
Except Windows system drive (usually the C drive)
When exporting files using the Export Utility, the available capacity of the startup drive is recommended to be larger than 1 GB.
When exporting a write-protected folder in the OS later than Windows Vista(R) using the Export Utility, it is actually configured to "%LOCALAPPDATA%\VirtualStore" instead of writing to the folder.
Example: C:\Users\user name\AppData\Local\VirtualStore
When the writing into OS is restricted because the security policy "User Account Control: Virtualize the error of writing of file and registry to each user location" is "Enabled", the following folders will be restricted:
%ProgramFiles%
Example: C:\Program Files
%Windir%
Example: C:\Windows
%Windir%
Example: C:\Windows
The OS that allows the use of the Export Utility for exporting files to CD-R/RW or DVD-R/RW is shown as follows. However, it is limited to the OS that support the CD-R/RW or DVD-R/RW drive being used.

Before the function of exporting files to CD-R/RW or DVD-R/RW media is used, use a PC and a CD-R/RW or DVD-R/RW drive, as well as media to verify the ability to do so.
If burning software or packet-writing software is installed, the DVD/CD writing function of the Export Utility may fail to run normally. When exporting files to CD-R/RW or DVD-R/RW using the Export Utility, uninstall the burning software and packet-writing software.
Since the power saving function is not supported when writing data to a DVD/CD using the Export Utility, ensure the power is always on. When the system is on standby, sleeping or suspended status, problems such as failure when using media may occur. In addition, under suspension status, the message of completed writing will be displayed, but in fact, the writing to the media may not complete normally.
When a DVD/CD device connects to the PC for the first time, if files need to be exported to CD-R/RW or DVD-R/RW media through this DVD/CD device, the system must be restarted. Otherwise, the function of writing into CD-R/RW or DVD-R/RW media may not run properly.
When burning a new CD using the Export Utility, the stream-writing mode (the session-at-once function in CDFS (Joliet mode)) can be used.
Written Files
File name: Maximum 64 characters (1 character for both SBC and DBC) (including extension).
Directory name: Maximum 64 character (1 character for both SBC and DBC) (including extension).
Full path length: Maximum 240 bytes (the delimiter of folder is counted as 1 byte, and one character of a file/folder name is counted as two bytes. One character of drive letter is counted as two bytes (Example: C: is counted as four bytes)).
The DVD/CD export function of the Export Utility regards only the empty media that does not record any information including volume labels as the target.
Definition of Empty Media
CD-R, CD-RW, DVD-R, or DVD-RW media that is not formatted after purchase.
CD-RW or DVD-RW media in which CD-RW/DVD-RW erasing has not been performed using the Export Utility
Files cannot be exported to the following media.
When disks are formatted to UDF format for packet writing (including the case without files in it)
When disks are formatted to CDFS format for stream writing (including the case without files in it)
The drive types, connection methods, and media types supported by the DVD/CD export function of the Export Utility are as follows.
Drive connection methods
ATAPI, USB 1.1/2.0, and IEEE1394
Media types
CD-R/RW (Maximum 700 MB is supported) and DVD-R/RW (Maximum 4.7 GB is supported)
The following table shows whether each type of media supports the Export Utility and export prohibition function.
Operation/Function of the File Export Utility | CD-R | CD-RW | DVD-R | DVD-RW | DVD-R DL (Note 1) | DVD+R | DVD+RW | DVD+R DL (Note 2) | DVD-RAM (Note 3) | |
|---|---|---|---|---|---|---|---|---|---|---|
Write | Windows Vista(R) | Y | Y | Y | Y | N | N | N | N | N |
Windows(R) 7 | Y | Y | Y | Y | N | N | N | N | N | |
Windows(R) 8 | Y | Y | Y | Y | N | N | N | N | N | |
Erase | Windows Vista(R) | N | Y | N | Y | N | N | N | N | N |

Windows(R) 8 | N | Y | N | Y | N | N | N | N | N | |
Export prohibition | Y | Y | Y | Y | Y | Y | Y | Y | Y | |
Y: Supported
N: Not supported
Note 1: It refers to DVD-R Dual Layer
Note 2: It refers to DVD+R Dual Layer
Note 3: Except when it is identified as a removable disk
Blu-ray and HD DVD are not supported.
A volume label can be specified for the media when writing files. Letters from A to Z, numbers from 0 to 9, and underscores (_) can be used in the volume label, and a maximum 16 characters can be specified.
The CD export function of the Export Utility is not closed. The Windows Explorer or burning software can be used to add data to the PC without DVD/CD writing prohibition. However, since the file Export Utility supports only the writing to empty media, data cannot be added. In addition, since it is in unclosed status, the unit that only processes the closed media cannot be accessed.
When the total size of source files to be exported is larger than the media capacity of export destination, the DVD/CD export function of the Export Utility cannot perform writing (multi-volume writing is not supported).
The size of the data that can be written varies with the writing media, number of files and structure of folder.
When multiple files are being written, the file size that can be written may not reach to the maximum capacity that is allowed to be written because information such as folder structure and file name must be saved.
When performing DVD/CD export through the Export Utility, work files should be written to the temporary directory of user. Therefore, do not change the temporary directory from the startup drive to another drive.
When the burning software is used to write files, media errors may occur if policies have been changed (writing to DVD/CD is not allowed).
The erase mode includes quick erase and complete erase. In quick erase mode, only the PMA (Program Memory Area) and TOC (Table of Contents) will be erased. In complete erase mode, all areas will be erased.
The file operation logs cannot be obtained from the Export Utility.
For some burning software, during writing prohibition, the burning may appear to have finished normally (but data are not really written into the media).
When performing DVD/CD writing by using the DVD/CD export function of the Export Utility, use the DVD/CD drive and media that are supported by the PC in use.
When exporting large number of files using the Export Utility, it takes certain amount of time to output the export logs (Normally, it requires 10 minutes when exporting 10,000 files).
The writing speed is the lower speed supported by the drive unit and media.
Fingerprints, dirt, dust, or scratches on the recording surface of the CD-R/RW media may result in abnormal data writing or erasing.
The media that can be closed during the burning process will be displayed as CD-ROM when the media type is a CD, and it will be displayed as DVD-ROM in the case of a DVD.
In the case of the media that cannot be erased and have been written, the disk total capacity displayed on the media erase window will be incorrect.
USB device prohibition
If using the USB device prohibition feature to allow only specified USB devices to be used, test operations with the USB device beforehand.
