## Syntax

 \ReadFile {file} file name of the file

## Description

The command `\ReadFile {filename`} is replaced by the content of the text file `filename`, if it exists. If it does not exist, no error message is generated and the compile process continues.

When no file extension is specified, the extension .tex is assumed.

Similar to the case with project structure commands such as `\environment`, `\ReadFile` causes ConTeXt to look in ancestor directories for the specified file.

## Example

We have a chapter 1 file, but no chapter 2 file:

```% chapter-01.tex
\subject{Chapter 1}

This is the first chapter.
```

The book file attempts to incorporate both chapters, using `\ReadFile{filename`}:

```% complete-book.tex
\starttext

% No extension specified, so .tex assumed

\stoptext
```

Compiling `book.tex` produces the following:

No error message is generated for the missing chapter 2, and the compilation completes successfully.

• \input: Similar to `\ReadFile` but the filename is not specified as an argument.
• \readfile: Similar to `\ReadFile` with additional options when file is not found.
