4.1 The File System
The 7705 SAR file system is used to store files used and generated by the system; 
for example, image files, configuration files, logging files, and accounting files. 
The file commands allow you to copy, create, move, and delete files and directories, 
navigate to a different directory, and display file or directory contents and the image 
version.
4.1.1 Compact Flash Device
The file system is based on a DOS file system. On the 7705 SAR, each CSM has an 
integrated compact flash device. The names for these devices are:
•cf3:
•cf3-A:
•cf3-B:
The first device name above (cf3:) is a relative device name in that it refers to the 
device local to the control processor on the CSM running the current console 
session. As in the DOS file system, the colon (“:”) at the end of the name indicates 
that it is a device.
The second and third device names (cf3-A: and cf3-B:) are absolute device names 
that refer directly to the device on CSM A or CSM B (CSM B applies only to chassis 
with redundant CSMs). 
The device cf3-B: does not apply to the following chassis because they do not have 
redundant CSMs: 
• 7705 SAR-A (both variants)
• 7705 SAR-Ax
• 7705 SAR-M (all variants)
• 7705 SAR-H (both variants)
• 7705 SAR-Hc
• 7705 SAR-W
• 7705 SAR-Wx (all variants)
• 7705 SAR-X
