Filter and backup even incrementally your files and folders, with Freebyte Backup
Freebyte Backup is a free tool that will help you to copy (and filter) a large number of files and directories from various sources into one backup directory.
You can backup all the files existing in one or more folders, or only certain file types.
Files are filtered according to their extensions. E.g. you can backup all .doc, .rtf, .jpg, .bmp files, ignoring all .exe, .dll and .txt files.
The program lets you define new file extensions that may not be that common.
Freebyte Backup supports also incremental backups.
