File Exists

File Exists

Type: file-exists  ·  Package: Filesystem Activities v1.0.0  ·  Output: boolean

Checks if a file exists at the given path and returns true or false. It is the safe way to anticipate errors: verify that a file is there before reading it, or wait for it to appear before processing it.

How it works

Returns true if there is a file in path, false if not. It does not throw an error if the file does not exist — that is what it is for. The result typically feeds an If.

Required parameters

Parameter	Editor	Description
path	expression	Path of the file to check.

Optional parameters

Ninguno.

Output

Returns a boolean: true if the file exists.

Example

Read a file only if it is present; If not, use a default value:

File Exists   path = = "C:/config/parametros.txt"   → output: existe
If   condition = = existe
 ├─ then:
 │    Read File   path = "C:/config/parametros.txt"   → output: config
 └─ else:
      Log   level = warning   message = "No hay archivo de parámetros; se usan valores by default"
