When you record and save a LoadRunner script in Vugen, there are a number of files that are created. Here’s what they are, and what they do and identification of the files you can safely delete..
Files Required for PlaybackDuring the course of recording and playback of scripts, the Vugen application will create many files, but only some of them are necessary for playback (either in Vugen or the Controller).
For example, say you have script named PerformancEngineer, with two Actions, Home and Forums, then the required files you would need in the PerformanceEngineer script directory would be:
* PerformanceEngineer.usr
* default.usp
* default.cfg
* globals.h
* Home.c
* Forums.c
* vuser_init.c
* vuser_end.c
* PerformanceEngineer.prm
Here’s what is in each file:
PerformanceEngineer.usr: Primarily, the .usr file defines which actions are used by the script. There are other properties which define which protocols are used and other settings, but most of the info
default.usp: Contains the run logic for the script
default.cfg: Contains the run-time settings (except for run-logic)
globals.h: The global headers file- visible and editable in Vugen
*.c (Action files): These are the action files containing your script code. You can edit these files in ny text editor, if you want. Sometimes it is easier than starting up Vugen
PerformanceEngineer.prm: Containes the parameter definitions
*.dat: Your data files, you can save these in the script directory or somewhere else, even a mapped network drive on a different server
Files Created During Vugen Playback
All of the files listed below can safely be deleted and not affect your ability to use the script.
result1: One or more result directories are created which contain script playback results
*.idx: The .idx files are binary “index” files created by Vugen for holding parameter values
PerformanceEngineer.ci:
combined_PerformanceEngineer.c: A list of #includes for all of your Actions
logfile.log, mdrv.log: random log files which you will probably never need to look at
mdrv_cmd.txt, options.txt: These text files contain commands and arguments for the script compiler and driver (mdrv) and are created dynamically, so you can safely delete them.
output.txt: This one is important. This file contains all of the log messages generated during script playback. The contents of this file appear in the “Output Window” section of Vugen
output.bak: A backup of the above file
pre_cci.c: Output from the C pre-processor, which contains all of the functions used in your scrip, from all of the Acitons and header files.
In summary, you can delete: *.txt, *.log, *.idx, *.bak, result*, pre_cci.c, combined_*, *.ci
Files Created During Recording
The ‘data’ directory in your script directory contains the script recording data. I usually delete this so it doesn’t get checked into my version control system, but you may want to keep it around if you use the graphical scripting mode and/or you want to compare playback vs. recording. The auto-correlation feature makes use of this data, too, but I haven’t had much sucess using that feature.
