Talk:LHA (file format)

LHA /LZH
There is a link from LZH to this page. What is the exact relation from LHA to LZH. Is it only a synonym? -- 217.86.161.131 14:26, 16 October 2006 (UTC)

LZH
From what I remember of the 80's, LZH stood for Lempel-Ziff-Huffman, and referred to the compression methods employed by the archiving program. Many archiving programs would create .lzh files, but only LHarc would create .lha files, though it was possible for one decompressor to decompress both types of files, so they may have been identical, or similar enough for 8-bit computers to deal with it.

This Wikiepdia entry states that it was developed in 1988, but I'm not sure that date is completely accurate. I used LZH/LHA archives on my Commodore 64 for some time before I ended up switching from C-64 to IBM-XT in January, 1988. In fact, I remember being frustrated at not being able to find a decompressor for DOS that could read my C-64 .lzh text files.

Sliding window?
The article linked to an article called "Sliding Window", but that article just redirects to a different article about "Sliding window protocol", which is pertaining to communication technology, not file compression.

Could someone elaborate on this just a little bit in the article if possible, please? I am curious. — Preceding unsigned comment added by 42.146.16.53 (talk) 18:08, 13 September 2016 (UTC)

Y2K11 bug?
I’ve tested this, packing a file with LHarc 2.13 under DOS. Both LHarc and  on Unix render the date as having the current year. AIUI it only affects LHarc on the Amiga? mirabilos (talk) 18:39, 23 June 2021 (UTC)
