I used https://geoconverter.hsr.ch/ to convert to OSM.

You need a suitable software like MapInfo to open a TAB file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your TAB file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a TAB file directly in the browser. Just drag the file onto this browser window and drop it.

Click on File (FILE), select Open, click on Computer and then the Browse button (FILE > Open > Computer > Browse). Make sure you have the All Files option selected from the filetype dropdown menu, then navigate to where your . tab file is stored, select it and then click on open.

ok

Clicking the GML with right mouse button will bring a menu from which you should select the Open with option
Next, select the Choose another app option and then using More apps open the list of available applications
The last step is to select Look for another app on this PC option supply the directory path to the folder where FME Desktop is installed. Now all that is left is to confirm your choice by selecting Always use this app to open GML files and clicking

Click inside the file drop area to upload the GML files or drag & drop a GML files.
Input spatial reference system for a map.
Select the map format and sizes (small, medium, large).
Click on 'Generate' button to render map.
Your map will be rendered using the input spatial reference.

Please forgive me, i will listen

i already gave you the answer, do you need me to explain further, you are really technical and expecting the whole picture, i am willing to reason and tell you the whole workflow.

i do not want to sound threatening, so please do not take offense to any messages or comments i make.

i am only trying to improve OSM, and would never vandalize

i just want the OSM community to know i am listening and are willing to listen

I did proper research into what sources are accepted and which are not

what do you mean by explain your workflow, i do not understand? i am confused

I did proper research into what sources are accepted and which are not, so you should know better before deciding to meaninglessly revert my license compatible edits to defeat the purpose of "free and editable".

different file types require different softwares, so it can vary, the answer is that i used all of these, as some are used as backups

about a week ago

you will see that i used an online viewer for .gml and .tab files but for .shp i used LSI Viewer
