What is a PA file?

A PA file is a compressed archive created by ConeXware PowerArchiver, a utility used to compress, encrypt, and back up data. It is compressed using the Advanced Codec Pack format, which includes various advanced filters and codecs used to optimize compression based on the file type, and may include FIPS 140-2 256-bit AES encryption. PA files may contain multiple directories or files compressed to save space for storage or transportation purposes.

More Information

The PowerArchiver Advanced Codec Pack format was released with PowerArchiver 2017. The format features two optimized compression modes: 1) "Optimized Fast" for faster compression and 2) "Optimized Strong" for stronger compression.

PowerArchiver uses the BWTS algorithm to mix data before AES encryption to better secure archives. This encryption method results in archives that are better protected than .ZIP and .7Z AES archive formats.
