Is it possible to uninstall files based on a condition during uninstall in Inno Setup?
Yes, it is possible to uninstall files based on a condition during uninstall in Inno Setup.
You can use the UninstallDelete
section in your Inno Setup script to specify files or directories to be deleted during the uninstallation process. Here's an example:
css[UninstallDelete]
Type: files; Name: "{app}\myfile.txt"; Check: ShouldDeleteFile
[Code]
function ShouldDeleteFile: Boolean;
begin
Result := (MsgBox('Do you want to delete myfile.txt?', mbConfirmation, MB_YESNO) = IDYES);
end;
In this example, the UninstallDelete
section specifies that the file myfile.txt
in the installation directory should be deleted during uninstallation. The Check
parameter specifies that the ShouldDeleteFile
function should be called to determine whether or not to delete the file.
The ShouldDeleteFile
function is where you can specify your condition for deleting the file. In this example, the function displays a confirmation dialog asking the user if they want to delete the file. If the user clicks "Yes", the function returns True
, indicating that the file should be deleted.
You can modify the ShouldDeleteFile
function to check any condition you want to determine whether or not to delete the file.
