# Large File Associations

On the General > Editors > Large File Associations preference page, you can specify which editors are used to open large files. You can associate file extension types and file sizes to an editor. Upon opening a file with the given extension, if the file is above the specified size, the associated editor will be used to open the file. When multiple pairs of editor and file size are specified for the extension of the file, the pair with the largest matching file size applies.

## File types list

- Add...: Adds a new file extension to the list of associated file types. In the resulting Add File Type dialog, type the file extension (e.g. simply "xml" or as a pattern "*.txt").
- Remove: Removes the selected file type from the list, along with all its associated editors and sizes.

## Associated editors list

- Add...: Adds a new editor and file size to the list of editors associated with the file type selected above. You can choose to be asked for an editor, upon opening a large file of the selected type. Or, you can choose the editor with which to open the file type beforehand. When choosing an editor in advance (by enabling and clicking the Choose Editor link), you can choose an editor to launch either inside the Workbench (internal) or outside the Workbench (external); click Browse in the now open Editor Selection dialog to locate an editor yourself if the editor you want is not displayed in the list.
- Edit...: Edit the selected editor and file size for the file type selected above. When editting an association which specifies an editor, you can click on the editor link to change the associated editor.
- Remove: Removes the association between an editor, file size and the file type selected above.
