1) I feel that windows 7 file copy is little slow in during network copy operations ( including LAN and wireless) should i disable that remote differential thingy? 2) Does windows 7 file copier do binary verification of the copied file so that file integrity is maintained like teracopy? 3) Howz teracopy vs windows 7 file copier? 4) i dont like using a third part file copier once i moved folder using teracopy and lost files. That is if copy is done by windows 7 file copy can i confirm that its done with integrity and file is not corrupted.. i want file integrity even if it is slow ... does windows 7 service pack 1 improves file copy performance?

Most reliable is Windows file copy. Even if doesn't show an option to verify, it verifies the files that are being copy or moved from one location to another.MCTS: Windows 7, Configuration
