Read File Bytes Activity


This activity reads the byte content of a file on the server. This activity should only be used to read binary content, such as an image, PDF or audio file. Using text content as input, such as a CSV file, will produce binary output. Binary content is not human readable. The Read File activity should be used for reading text content. Binary content is the raw numbers, known as bytes, that make up a file. More information on the difference between binary and text files can be found here.


The Read File Bytes activity could be used to read a PDF file on the server.




Type: String

The path of the file to read on the server. The file system or network path must be valid and the server administrator must configure the appropriate permissions to allow reading of the file.

Attempting to read a file that does not exist will fail.



Type: Number[]

The byte content of the file.

Bytes are the raw binary values that represent content. A byte array is represented by a list of numbers between 0 and 255. This content is not human readable, and should be used as input to other file activities, such as the Convert Bytes To Text activity.
