+			Similar to the HTTP request you can read from files by putting the emoji 📝 in front of an absolute path to
+			a file. Other than the HTTP request you are able to write into a file using that method. Since line breaks
+			are not supported you can use a variable index to write to or read from specific rows (0-indexed: meaning
+			the first row has index 0, the second row index 1 and so on). Specifiying no index will always read or write
+			the first line.<br>
+			<strong>Example:</strong><br>
+			<code>{% print 📝C:\path\to\file.txt %}</code> - prints the contents of the first row of the file<br>
+			<code>{% set $num > 📝C:\path\to\file.txt[1] %}</code> - writes the contents of $num into the second row of the file<br>
+			<code>{% add $str > 📝C:\path\to\file.txt %}</code> - appends the contents of $str to the first row of the file
