So if you plan to send an archive with this new RAR 5 format, you have to keep in mind that compatibility issue of this RAR 5. If your friend or receiver of the RAR 5 archive files, can’t open that files using the 7-zip or other archivers. They might have receive errors like “File is corrupt” so something like this.
