Dynamic
files
Dynamic files
The logic analyzer's file system uses dynamic files for configuration
information and data. This means
that
applications
such
as
File Manager
or
a
spreadsheet
cannot determine
the
size of
the
files until
they
are
retrieved.
When you view
the
file statistics for these files, you will
see
file sizes
of
0
bytes
or
1 byte. The 0-byte size indicates
that
the
file is empty. The 1-byte
size indicates that
there
is information in
the
file.
If
you transfer
the
file of
interest
to
your
PC
or workstation, you will
be
able to
see
the
actual file size.
Known
Incompatibilities
Some operating systems
and
applications may exhibit
unexpected
behavior
when
working with
the
dynamic files from
the
logic analyzer. The
"%
complete" display may appear incorrect during file transfers. This does
not
affect the transfer or
the
contents of the file. Once you have saved
the
file
in
your local environment,
the
correct
"%
complete" will
be
displayed
during future retrievals.
Your applications might only retrieve one or two
characters
from a file
that
you believe has many more characters in it. To work
around
this problem,
copy
the
file
that
you want
to
work with from
the
logic analyzer to your local
computer. Use the local copy as your working copy.
SUN Operating
Systems
The file copy commands in
the
SUN
workstation
and
Solaris operating
systems will not work with
the
dynamic files like
those
used
in
the
logic
analyzer.
You
can use
the
dd
command instead
of
using
the
cp
or
cat
commands.
