BitCopy is a file copy program for Windows. Create copy sets (jobs) to copy files between any local or remote directories. Select files to copy at each level of a directory hierarchy using a filter expression involving file name/path/date/size. Use AND/OR/NOT to build filters of arbitrary complexity. Use different filters for different subdirectories. Build and test filters interactively. Efficient and robust design can handle millions of files and terabytes of data in a single copy set. Overwrite only changed files, or always overwrite files, or never overwrite files in the target directory.
