Can I delete all resources from a project in bulk?

Deleting resources in bulk is not an option that is offered via Transifex Web Interface.
However, this can easily be done via Transifex Client. Once it is installed, it’s a matter of three commands to achieve what you want:

  1. Initialize a Transifex project:
    $ tx init
  2. Synchronize your project on with your local instance:
    $ tx set —auto-remote
  3. Delete all the resources in a project
    $ tx delete -r dproject_slug.*

The last command will delete all the resources that are hosted at your project in Transifex.

In case you want to remove specific resources in a project, then you can use the following command line:
tx delete -r project_slug.resource_slug
