im on windows now and it is a 7z file and when i extract it it is esp but it is openend with notepad so do i still just put it in the data folder
Yes, you put a .esp file in the Data folder, then make sure it's checked in the Data Files display (or in OBMM, if you use that).
If there were other folders, such as Meshes or Textures, along with the .esp, copy those to the Data folder too. You'll get warnings about overwriting folders that already exist. Those are OK; click "Yes to all" or whatever comes up to OK them.
