# diffcopy
Copy modified files from sub directories into one target directory.
diffcopy checks which files have changed in a directory including its subdirectories based on the file name, file size and modification date.
These files are then copied to a target directory while retaining the original modification date.
If a file with the same name is stored in two or more directories, the file with the highest modification timestamp is copied.
