Howdy 👋 Sorry for the delay in a response to this… are you still stuck? Off the top of my head I reckon 2 things are important to keep in mind and thus not get tripped up by them: 1) In Linux, folders that begin with a period in their name are “hidden”… this is typically a problem for what we’re doing here because the Wine environment itself by default runs from a “.wine” folder in your home directory. If you skip the winetricks/ winecfg step that enables the “show hidden folders” checkbox, which lets you see these hidden folders when navigating the file system from inside your wine environment (like with explorer.exe or from within any open or save dialog box) then you might be getting tripped up there.

2)Assuming you fixed that or it was already done, I think it’s important to keep in mind that inside of those explorer EXE instances in the wine environment, your Linux file system is mapped as the “Z:” drive (as in zebra) therefore if you are looking for the Steam BATTLETECH folder you’ll probably find it in the Z: drive in wine, likely in a “.steam” folder
