Paragon-X: How can I manually retrieve capture files?

If you require capture files from a previous session, it may be possible to retrieve them from the auto-save directory. Paragon-X automatically stores all capture data in this directory; files in this folder are usually stored for 30 days.
The auto-save folder location can be found using the File→Resource Management menu option in the Paragon-X application:
Clicking in the file location box allows the location to be copied (using <ctrl-a> then <ctrl-c>) for pasting into Windows Explorer.
You may also change the default retention time used for capture files, Since capture files can be large, you may want to reduce the time for which they are retained.
Auto-save file types
The capture files are in a folder called AutoSave in the directory above. The naming convention is: <IPaddress of instrument><Start Time of capture>_<Test type>.cpd
For example, the file 192-168-3-100_20160212_11-39-44_PTP.cpd is the data for a PTP capture which was run on a Paragon-X with IP address 192.168.3.100 starting at 11:39:44 on 12th February 2016.
Each type of Paragon-X measurement capture file has a filename which indicates the type of test data it contains:
| File name | Content |
|---|---|
| _PTP.cpd | PTP main capture file |
| _SE.cpd | SyncE measurement capture |
| _1ppsAcc.cpd | 1PPS Time Error (Absolute) measurement capture |
| _1ppsWan.cpd | 1PPS Time Error (Relative) measurement capture |
| _2MWan.cpd | 2M wander measurement capture |
| _T1Wan.cpd | T1 wander measurement capture |
| _E1Wan.cpd | E1 wander measurement capture |
| _ATOD.cpd | Time of Day capture |
| _AP.cpd | All-packet capture file |
| _NTP.cpd | NTP capture file |
| _CH.cpd | CES capture file |
| _PA.cpd | Services mode capture file |
| _OM.cpd | OAM mode - multimeg flow capture file |
| _OS.cpd | OAM mode - singlemeg flow capture file |
Loading multiple captures into the Paragon-X Application
If you want to load all the capture files (measurement types) created during a particular session into Paragon-X:
- In Windows Explorer, identify all the relevant files and select them
- Right click and choose 'Send to Compressed (zipped) folder'.
- Rename the resulting .zip file to .clxz
- Use File→Import to import this bundle into the GUI for further analysis.
Your AutoSave folder may also contain a number of .cpz files. These are generated by the Paragon-X GUI when loading .cpd files, and can be ignored or deleted.
