TeamViewer is an excellent screen-sharing and file-transfer app that can be used to facilitate business collaborations, remotely access a second computer, or help distraught relatives diagnose and cure computer problems. Along with being free for noncorporate use, it gives users precisely the tools they need to share screens securely, send files with a minimum of hassle, control access rights, and even flip which user has control.
TeraCopy from Code Sector is a free file-copying utility that offers more speed and security than Windows. It’s a compact tool that can quickly copy or move single files or batches of files to any directory you select, but it does much more, such as automatically calculating CRC checksum values to speed up the validation process. It also skips bad files during the copying process, displaying them at the end of transfers so you can see just which ones need replacing or other attention.
