Features of Bandizip's ZipX

  • Offers much better compression than the traditional zip files with the LZMA algorithm
  • Saves the file name as Unicode (UTF-8); International filenames won't be corrupted
  • Supports AES256, which is the strongest encryption available for password protection
  • Supports the LZMA algorithm. This algorithm is slower than the traditional DEFLATE algorithm, but the compression rate is significantly higher.

Cons of ZipX format
