範例:

  • 刪除檔案:7z d archive.zip *.bak
  • 解壓縮到目前資料夾:7z e archive.zip
  • 解壓縮所有的.cpp檔案案件到指定資料夾:7z e archive.zip -oc:\soft *.cpp
  • 顯示壓縮檔內的資訊:7z l archive.zip
  • 依壓縮檔內的檔案路徑解壓縮到指定資料夾:7z x archive.zip -oc:\soft *.cpp
更詳細的內容直接看到7-zip.chm即可。

做了一點小測試:將資料夾內30個檔案大小共260,823,040 Bytes的檔案(SQL Server資料庫備份出的資料檔案),分別使用7-Zip、PkzipC、WinRAR 3.0
壓縮,大小分別同下:
  • 7-Zip: 43,791,855 Bytes
  • WinRAR: 50,415,283 Bytes
  • PKZipC: 63,701,625 Bytes
獲勝的是7-Zip。
