6-1 Overview
6-1-2 File Operation Restrictions
This section explains which operations are possible on 
files stored in each directory.
When required, the following operation tables distinguish 
reading and writing from partial reading and writing.
Read: Read data sequentially from the start to the end of 
the file.
Partial read: Read only a part of the data in the file.
Write: Write data sequentially from the start to the end of 
the file.
Partial write: Write data to a part of the file only.
Root directory
a) Only when “NAMING FORM” on the FILE NAMING  page of the 
OPERATION menu is set to “FREE”
b) Only files which can be written by XDCAM
Notes
• Directories cannot be created in the root directory.
• The directories in the root directory (Clip, Edit, Sub, and 
General) cannot be deleted or renamed.
Clip directory
a) With firmware version 1.5 and higher, files having a user-defined name in 
the “C*” part can be handled.
b) Possible with firmware version 1.5 and higher.
c) Only files which are 2 seconds or longer in length, in a format matching 
the line mode format (525/625) and recording format (IMX50/IMX40/
IMX30/DVCAM and number of audio channels) of the recorded sections 
of the disc, and which can be overwritten by XDCAM.
d) Only when the Write Inhibit tab on the disc is set to enable recording. With 
firmware version 1.4x and lower, only the most recently recorded clip may 
be deleted. With firmware version 1.5 and higher, any clip may be selected 
and deleted.
e) Only files which can be written by XDCAM
f) With firmware version 1.5 and higher, when the "C*" part of a C*.MXF 
file name is changed, a C*M01.XML file with the same name in the “C*” 
part is also changed automatically.
g) When a C*.MXF file is created, a C*M01.XML file with the same name 
in the “C*” part is created automatically.
h) When a C*.MXF file is deleted, the C*M01.XML file with the same name 
in the “C*” part is also deleted automatically.
Notes
• Directories cannot be created in the Clip directory.
• When the following operations, supported by version 1.5 
and higher XDCAM devices, are carried out on a disc, 
then it becomes impossible for version 1.4x and lower 
XDCAM devices to record new clips or delete existing
