File functions

Learn about file functions in the Digibee Integration Platform and how to use them.

The file functions make queries to metadata and make validations in files and are available for components that support Double Braces expressions. To know how to provide information to the components using this resource, refer to Double Braces Functions.

FILEEXISTS

Checks if a file exists in the virtual directory of the pipeline deployment.

Syntax

FILEEXISTS(file)

• file: name of the file in the virtual directory of the pipeline

The function returns true when the file is found and false when it's not found.

FILESIZE

Returns the size of a file in the virtual directory of the pipeline deployment.

Syntax

FILESIZE(file)

• file: name of the file in the virtual directory of the pipeline

Let's say you need to obtain the size of the file created one step before the use of the File Writer component. If its file name configuration in File Writer was file.txt, then use the following extract in the JSON Generator component:

{
"fileSize": {{ FILESIZE("arquivo.txt") }}
}

The result would be:

{"fileSize": 1000}

• fileSize: the size of the file (in bytes).
