Files Manager

The Files manager tool is available on the left menu of the Design view, in the Tools section.

It lets you upload and delete files. These files can be:

  • CSV variables content,
  • POST Http request bodies,
  • scripts,
  • hosts file to be be appended at the end of the load generator’s hosts file (during validation and runtime).
  • JMeter plugins jar files.
  • remove-files.txt: List of files to be removed from JMeter folder. This can be used to prevent compatibility issues with some library versions.

Selecting an existing file is done using the select box. If you use many files in your project you can type the name of the file you are looking for to filter the displayed file.

Simply click on any filename to select it.

To upload a file click on the plus button located at the right of the selector. A Choose File button appears. Click on it and select a local file. It is automatically uploaded and selected.


If there are no files available in the current project, only the file upload option is visible. Filters may apply for the files you can select or upload. For example CSV variable only accept .csv files.
