# User manual for GHex

GHex is a simple binary editor. It lets users view and edit a binary file in both hex and ascii with a multiple level undo/redo mechanism. Features include find and replace functions, conversion between binary, octal, decimal and hexadecimal values, and use of an alternative, user-configurable MDI concept that lets users edit multiple documents with multiple views of each.

  游標偏移量是指檔案開頭與各行第一個位元組之間的距離。 依預設值，GHex 會在十六進制檢視的左邊，顯示游標偏移量欄位。

左邊的顯示窗格

  顯示區域左邊的顯示窗格，會以十六進制顯示檔案。

右邊的顯示窗格

  顯示區域右邊的顯示窗格，會以 ASCII 制顯示檔案。

Type conversion dialog

  The type conversion dialog below the display area displays the value of the selected character in several different numeric types.

## 使用

### 編輯檔案

如果要編輯檔案，請執行下列步驟：

1. 請按一下檔案的十六進位或 ASCII 檢視。 檢視若為作用中，則會顯示完整的游標。 檢視若為非作用中，則只會顯示游標的外框。

2. 請使用下列任一種方法，在檔案中移動游標：

   - Use the scrollbar on the window or the arrow keys on the keyboard to scroll through the file.

   - 請選擇編輯到位元，以十進制或十六進制鍵入游標偏移量，然後按一下確定。十六進制數值的格式，必須為 0x 加上偏移量，例如 0x3。

3. Edit the ASCII format in the same way you edit a normal text file. To edit the hexadecimal format, use the values 0 to 9 and a to f.

To insert data and not overwrite existing data, choose Edit Insert Mode.

To cut, copy, and paste data, choose Edit Cut, Edit Copy, and Edit Paste.

To undo an edit, choose Edit Undo. To redo an edit, choose Edit Redo. The number of previous edits that you can undo is determined by the Maximum number of undo levels setting in the tabbed section of the Preferences dialog.

### 儲存檔案

您可以使用下列方式儲存檔案：

- 如果要將變更儲存至目前的檔案，請選擇檔案儲存。

- 如果要用新的檔名儲存目前的檔案，請選擇檔案另存新檔。請在選擇檔案儲存緩衝區對話方塊中，輸入檔案的名稱，然後按一下確定。

- Uses the HTML filename that you specify as the basis for the filename.

- Appends a page number to the filename to differentiate the files.

For example, if you specify the filename `log.html`, GHex creates a series of HTML files named `log00000000.html`, `log00000001.html`, `log00000002.html`, and so on.
