What are R51 files and how to open them

What is a R51 file?
A .R51 file is a Split WinRAR Archive (part 53) file.
Files with the .R51 file extension are split archive files created by older versions of WinRAR. Newer versions name the files name.partXX.rar.
WinRAR and other compression tools take collections of files and compress them into a single archive file, normally to save hard drive space and to make distributing the file collection easier.
Archive files can get very big, and sometimes it is necessary to split them into smaller parts to fit on CDs or USB drives. When an archive file is split, each part of the archive is assigned a numbered file suffix. Files with the R51 extension are part 53 of the split archive (the first part is named .RAR, second part .R00, third part .R01, etc.).
To access the content of the .R51 file, you will need to have all the archive part files in the same folder and open the first file (with file extension RAR) with your compression tool.
