Quotes from the program documentation:

UHBC is a blocksorting compressor optimized for high compression ratios. The current version is still in an experimental state, but because the results are close to the world's best, I decided to release this program as public BETA version. It is still under development, so you use this program at your own risk. UHBC doesn't use any data filters or transformations before BWT.

UHBC is a file-to-file-compressor, not an archiver. So it doesn't store name, time/date or attributes of the original file. There is no check for existing files and there is also no file verification after decompression.

The compressor is featured in the BWT comparison.
