A file can easily be inserting into another file using the 'Edit > Insert File...' menu option. Position the cursor at the address to insert the file and click the Insert File menu option or press Ctrl+I. Select any file with the file dialog box that is shown and click the Open button. The file will instantly be inserted into the current file. Note that files cannot be inserted into drives or processes since the file size of drives and processes is always fixed.

NOTE: 010 Editor employs a read-on-demand data engine that allows even huge files to be instantly inserted. As a result, the inserted file should not be deleted until the edits have been saved to disk (see Introduction to the Data Engine for more information).
