4.11.1 How to Create a Multisegment Recording
To create a Multisegment recording:
1. Select Setup > Recording Options to open the Recording Options dialog at the
General tab. Click Switch to Advanced Mode.
2. Check the box marked Save as Multisegment trace.
3. In the box marked MB Segments, enter a value of 4 to 128 MB.
4.11.2 What Gets Created
Multisegmenting produces an index file and segmented CATC Trace files. The default
name of the index file is data.pem.
The index file and the segmented CATC Trace files are stored in a directory named after
the index file. The directory is named data_pem_files. Below this directory additional,
sequentially numbered sub‐directories (up to 100,000) hold the segmented CATC Trace
files. These sub‐directories bear simple numerical names: 00000 to 00999. Each of these
subdirectories can hold up to 100 sequentially numbered segment files. Collectively, the
entire directory structure can hold up to 10 million files.
Example
If you create a 1010 MB recording using 10 MB segments, the following files and sub‐
directories are created:
data.pem (This is the index file.)
data_pem_files\00000\segment_00000.pex
data_pem_files\00000\segment_00001.pex
...
data_pem_files\00000\segment_00099.pex
data_pem_files\00001\segment_00100.pex
data_pem_files\00001\segment_00101.pex
Note: An additional index file is created called segments.col. This is an internal system file
that users should not modify.
