Abylon FILECOPY is an extension for the Windows File Explorer. Menu file lists can be copied from the clipboard to the target directory via the right mouse button. This way only those files are copied, whose file content has changed. This doesn’t depend on the file name, because these files are simply renamed. Especially with large amounts of data, such results are an immense time saving. Further advantages include the overwriting of the used files and the optional execution of the copy process with administration rights. The options include the synchronization of directories or the simple search for files or file contents.
