FOpen Function

Action

Opens or creates a file with the specified filename and returns a handle to the opened file.

If the file name includes a directory name, the file is opened in the specified directory. Otherwise, Silk Performer searches for the file in the directory where the test script is located, in the data directory, in the results directory and in the project directory.

If you are going to use remote agents for the load test, you should store your data files in the Data directory or in the directory where the test script is located. Note that in any case you have to add the data files to your load-testing project.
