x[N] y[N] z[N] t[N]

is the number of samples acquired. The file saves x, y, z,andt as doubles

at 8 bytes each.

Removing a File from the Target PC

You can remove a file from the target PC by using xPC Target methods o n

the host PC for the

xpctarget.ftp object. If you have not already done so,

close this file first with

fclose.

Use the method syntax to run an

xpctarget.fs object method. The syntax

method_name(fs_object, argument_list) can be replaced with

fs_object.method_name(argument_list)

Getting a L ist of Open Files on the Target PC

You can get a list of open files on the target PC file system from the host PC

by using xPC Target methods on the host PC for the

xpctarget.fs object. Do

this to ensure you do not have files open unnecessarily. The target PC file

system limits the number of open files you can have to eight.
