Import mesh but file format missing .obj and .ply in open file dialog

[Lun Yi]

Built meshlab by Qt extension of Visual Studio 2019, when importing mesh, I did not see the file formats of obj or ply in file dialog window, so I cannot open/import mesh obj or ply format file in the folder.

What is the problem ?

help, thanks
