我想用SDL2的library,下載SDL2-devel-2.0.8-mingw.tar.gz (MinGW 32/64-bit)後卻發現不會解壓縮,其檔案類型為GZ 檔案

我嘗試過在其官網下載32-bit x86的7-zip,execute後進度條是滿的,卻沒有下載完成,只顯示"7-Zip 18.05 is installed",過了半小時仍是這樣

我也嘗試過下載Gnuwin,然後開啟命令提示字元,按照Gnuwin的路徑輸入"C:\Program Files (x86)\Gnuwin32\bin\gzip" SDL2-devel-2.0.8-mingw.tar,卻顯示gzip: SDL2-devel-2.0.8-mingw.tar: No such file or dicectory
但我明明是按照gnuwin的壓縮檔名稱打啊, 還嘗試過打SDL2-devel-2.0.8-mingw.tar.gz,也顯示同樣字眼,還是說要把gnuwin的位置也打上?

又或者可以不下載SDL2-devel-2.0.8-mingw.tar.gz (MinGW 32/64-bit)而下載其他版本嗎?我是要用在visual studio的C language,但網絡教insert library的教程只有SDL2-devel-2.0.8-mingw.tar.gz (MinGW 32/64-bit)的版本,如果是其他版本又要怎樣insert library?

各位高手求指教,我只想在visual studio的C裏用上SDL2的library啊,卻苦苦糾纏了幾個小時,仍沒想出辦法來
