Local Storage Location

When you run the command wrangler dev, any data related to R2, as well as other resources, is saved in the .wrangler/state directory within your project folder. This directory is automatically created if it doesn’t exist. The files uploaded during local development are stored in a subdirectory under .wrangler/state, specifically in a path like .wrangler/state/../r2/Blob

Customizing Storage Location

you can use the --persist-to flag with the wrangler dev command. This allows you to specify a different directory for local storage, which can help in organizing your project or separating local development data from other files
