Error When saving it says? .... write_mesh: Unknown file extension *filename* ( .ply /.obj are supported ).

[Net-Sensei]

Iam keep importing obj format mesh and try to fix bad geometry and it fixed it that's great. but when i finalize it and try to save as obj then it gives me this error ...in windows

and solution is just put extension in the end. For example (mesh.obj or .ply) while saving i mean why it cant do it automatically

"Very good~ Can it support formats such as glb and obx?"
