@ali hassan - can you show us the code that calls uigetfile? What OS are you using? Please provide more details.

Hi,

The best fix is to upgrade to MATLAB R2025a as this issue has been fixed starting this release.

Refer to this MATLAB answer:

Some workarounds for releases before R2025a:

1.You can keep the app window foregrounded by setting the UI figure’s WindowStyle:

% In startupFcn or after creating the UIFigure:
app.UIFigure.WindowStyle = 'alwaysontop';

This property exists for uifigure starting in R2021a. Note that it pins your app above other windows.

2. Create a hidden dummy figure before uigetfile and delete it right after. This prevents your app from minimizing or falling behind other windows.

f = figure('Visible','off','CloseRequestFcn','');   % dummy owner
[fn, fp] = uigetfile({'*.*','All files'}, 'Select a file');
delete(f);        

Hope this helps!
