## 30.5 Edits Between Files

When you give a yank buffer a one-letter name, you have a convenient way to move text from one file to another. Named buffers are not cleared when a new file is loaded into the vi buffer with the `:e` command (30.4). Thus, by yanking (copying) or deleting text from one file (into multiple named buffers if necessary), calling in a new file with `:e`, and putting the named buffer into the new file, you can transfer material between files.

The following example illustrates how to transfer text from one file to another.

Keystrokes | Results
--- | ---
> `"f4yy` |
>      With a screen editor you can scroll
>      the page, move the cursor, delete lines,
>      insert characters, and more, while seeing
>      the results of the edits as you make them
| Yank four lines into buffer f.
> `:w` |
>      "practice" 6 lines 238 characters
| Save the file.
> `:e letter` |
>      Dear Mr.
>      Henshaw:
>      I thought that you would
>      be interested to know that:
>      Yours truly,
| Enter the file letter with `:e`. Move cursor to where the copied text will be placed.
> `"fp` |
>      Dear Mr.
>      Henshaw:
>      I thought that you would
>      be interested to know that:
>      With a screen editor you can scroll
>      the page, move the cursor, delete lines,
>      insert characters, and more, while seeing
>      the results of the edits as you make them
>      Yours truly,
| Place yanked text from named buffer f below the cursor.

If you yank into a buffer and type the buffer name as an uppercase letter, your new text will be added to the text already in the buffer. For example, you might use `"f4yy` to yank four lines into the buffer named f. If you then move somewhere else and type `"F6yy`, with an uppercase F, that will add six more lines to the same f buffer - for a total of ten lines. You can yank into the uppercase buffer name over and over. To output all of the yanked text, use the lowercase letter - like `"fp`. To clear the buffer and start over, use its lowercase name (`"fy...`) again.
