What is a .tfstate file?

File extension details and usage information

A TFSTATE file is a Terraform State file used by HashiCorp Terraform, an open-source infrastructure as code (IaC) software tool. This file plays a critical role in Terraform's operation by mapping real-world resources to your configuration, keeping track of metadata, and improving performance for large infrastructures. It is stored in JSON format and contains a cache of the state of the infrastructure managed by Terraform. This state is used to determine which changes to make to the cloud or physical infrastructure to match the desired configuration. Because it contains sensitive information such as database passwords, private keys, and API tokens in plain text, it must be secured carefully, often using remote state backends like AWS S3, Azure Blob Storage, or HashiCorp Consul with encryption enabled.

Common questions about .tfstate files

To open a .tfstate file, use software that supports this file format.

  • HashiCorp Terraform CLI
  • Visual Studio Code
  • Notepad++
  • Sublime Text
  • BBEdit

Open the file in compatible software and look for options such as Save As, Export, or Convert. If no export option is available, the file may require a specialized converter or the original application that created it.

  1. Verify that the file extension is correct.
  2. Install or update compatible software.
  3. Try another application that supports this format.
  4. Check whether the file is corrupted, incomplete, or encrypted.

A file extension alone does not guarantee whether a file is safe or unsafe. Only open files from trusted sources, scan unknown files before opening them, and be especially careful with executable, script, archive, and document files.

File safety tips

Use caution with unknown files

Only open files from trusted sources. Before opening a .tfstate file, scan it with antivirus software, verify that the file extension is expected, and avoid running unknown executable, installer, macro-enabled document, or script files.
