The 7zFormat.txt in 7z920.tar.bz2 is more up-to-date than the one in lzma920.tar.bz2, but neither is decipherable without reading the reference implementation (of which only the C++ version is complete), and the reference implementation differs from them (eg.

For 2.x can we use a RandomAccessFile based API for at least reading files, since seeking through a one-pass InputStream requires O(n) memory? > Damjan, you forgot to add yourself to the POM. :-) I thought I'd first commit a few more patches so I earn the right to be a "<developer>" :). > Stefan > Damjan --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org For additional commands, e-mail: dev-h...@commons.apache.org
