All about R1 Files
The R1 file type is primarily associated with WinRAR.
What is an R1 file
R1 files mostly belong to WinRAR by RarLab. R1 files are part of compressed archives created by WinRar, a compression software.
- Main Usage: The compressed archive created through WinRar is stored as an R0 file. This may be a standalone archive file, in which case, all the data is contained within the single R0 file. Alternatively, it may be part of a multi-volume archive, where the contents of the archive are split across numerous files. Other parts of the multi-volume archive would use the extensions R01, R02 and so on, or R1, R2, etc. The purpose of this compressed archive format is to group files into a singular archive and to reduce the disk space required to store this data. Splitting the data using a multi-volume archive can be used to facilitate sending this data over protocols which impose limits on individual file size, such as email. This format is similar to other multi-volume compressed archives, such as the C00 extension, which is used by WinACE. The C00 format uses a similar naming convention to the R0 format, as both increment the digit by 1 for each part of the archive.
