Windows file archive compressed using UHarc compression; may create smaller archives than .RAR compression, but decompression typically takes longer.

Important: UHarc archives created with UHarc 0.4 are not compatible with later versions, such as UHarc 0.6, and vice versa. UnUHarc, included with UHarc 0.6 can be used to decompress UHarc archives created with version 0.6.
