Compressed archive (SAR)
SAR is a file extension for an archive file used with SAP business systems. SAR files contain compressed versions of delivered files and executables used by the SAP CRM. SAR files can be opened by the SAPCAR compression utility. SAPCAR is a command-line compression utility.
The prior version of SAPCAR was called CAR, and created CAR files. SAR files are the result of changes in the SAP CRM which required changes to the compression that was used, hence the introduction of SAPCAR.
