Self-Uniting: Operation
The Operation page decides how the Self-Uniting app behaves on the recipient's computer. Its settings are saved in the .ini file written next to the app.
Find it under Self-Uniting > Operation in the navigation pane of the Split view. The page is split into six categories. Choose one in the Category list, or step through them with the Previous category and Next category buttons. The categories stay available when the app is off, but their settings are greyed out; see Add the Self-Uniting app to the piece set.

Welcome message
Section titled “Welcome message”Shown when the app starts
Section titled “Shown when the app starts”The text the app shows in its window before the recipient starts. The default text reads:

{desc} | The description of the set. |
{size} | The size of the original, in KB, MB or GB. |

Then delete the restored file
Section titled “Then delete the restored file”Available when Wait until the app it opens ends is on. The app deletes the restored file when the opened program ends. If the opening gave no program to wait for (the file went to a program already running), the file is kept and the app says so.

Silent mode: no window, works in the background
Section titled “Silent mode: no window, works in the background”Off by default. The app shows no window at all and answers no questions: it stops at the first problem, and reports the result only through its exit code.
Add a header image
Header image
Section titled “Header image”Image file (.bmp, .png, .jpg)
Section titled “Image file (.bmp, .png, .jpg)”A picture shown at the top of the app window: a bmp, png or jpg image, 353 × 65 pixels or any wider shape, fitted to the window width. Leave the field empty for the default header. Browse… opens a file picker.
GSplit copies the image next to the app under its own file name. If the file cannot be found, the split log shows a warning and the app uses the default header. The Linux console version shows no image.
