上列的imageformats(圖像格式)，codecs(編碼)，sqldrivers(數據庫設備)文件夾均是[QTDIR]\plugins\目錄下用到，當然具體添加哪些根據具體程序來。
目錄主結構下的QtCore4.dll、QtCored4.dll等是根據Qt程序添加的模塊來，如.pro文件中的QT+=gui，QT+=core，QT+=sql等，就需要添加相應的dll。文件位於[QTDIR]\bin。
主目錄中msvcp100.dll 和 msvcr100.dll屬於VS2010的動態鏈接庫，位於 F:\Program Files\Microsoft Visual Studio 10.0\VC\redist\x86\Microsoft.VC100.CRT（本機）。
