[@Peter Blaise] Yes, BitSilo makes standard copies of files. The files are organized in the archive based on options you select for the Backup Set. For example, if in the Backup Set Edit dialog you select the options “Folder archive” and “Full directory names” you will be able to Windows Explorer to browse the backed up files. Other options organize the files differently for efficiency, e.g. files can be saved in a standard Zip archive (also browseable directly via Explorer) or you can choose to “index” the directory names, which reduces directory names to an integer code rather than the full text of the directory path. A little experimentation with these formats should make this clear.
