Last time I have found iexSevenZip and I enabled IESupportCompression. I can create new archive without problem but I can not find out how to update an existing archive file (add new files). I have found the [url=https://sourceforge.net/p/sevenzip/discussion/45797/thread/77e5ae25/#a436/98c4/c6ba]following hint[/url]: Update operation:
1) reads a.7z 2) creates new archive b.7z that using a.7z 3) renames b.7z to a.7z (if OK, and if you want it),
That why you still need IInArchive.
Could you help me with some example how to implement 2)
