Por padrão, ele colocará os arquivos baixados e extraídos no diretório que vem com a instalação do Python, que é o **ambiente global**.

## O que são ambientes virtuais { #what-are-virtual-environments }

A solução para os problemas de ter todos os pacotes no ambiente global é usar um **ambiente virtual para cada projeto** em que você trabalha.

Por defecto, pondrá esos archivos descargados y extraídos en el directorio que viene con tu instalación de Python, eso es el **entorno global**.

## Qué son los Entornos Virtuales { #what-are-virtual-environments }

La solución a los problemas de tener todos los paquetes en el entorno global es usar un **entorno virtual para cada proyecto** en el que trabajas.

// The above means that any added/deleted fields are incompatible.
// Make sure to bump the internode version at storage-rest-common.go
type RawFileInfo struct {
	// Content of entire xl.meta (may contain data depending on what was requested by the caller.
	Buf []byte `msg:"b,allownil"`
}

// FileInfo - represents file stat information.
// The above means that any added/deleted fields are incompatible.

It is not encrypted, so, anyone could recover the information from the contents.

But it's signed. So, when you receive a token that you emitted, you can verify that you actually emitted it.

That way, you can create a token with an expiration of, let's say, 1 week. And then when the user comes back the next day with the token, you know that user is still logged in to your system.
