Delphi System.zip patch with ZIP64 and LZMA supports
I think that abort procedure must be added.
Please add demo for Decompression from LZMA, thanks.
In the TZipFile.OnProgress-Event the Position resets sometimes.
I have a 12 GB File and was at position 4,294,770,688 of 13,123,635,712. After that again at 819,200 / 13,123,635,712.

TLZMAEncoderStream and TLZMADecoderStream implement TStream interface incorrectly, that is why it is impossible to use them with stock System.Zip, or any other code, that expects TStream descendant. Please, implement support for reading and writing in chunks from any buffer, as expected by TStream.
I know that you are not the one that wrote this part but do you know why there is an hard-coded file limit in System.Zip.pas ? I'm not able to find a reference a out this limit on Internet.
if FFiles.Count = $FFFF then
raise EZipException.CreateRes(@SZipExceedNumberOfFiles);
Hello, I've been here for several hours and I can't do the compression and even the Unzipping in the LZMA format could not attach a demo project to me.
Grateful.
I have reported (and solve) an issue to Embarcadero : RSP-37093
You can download System.Zip2 corrected in TestZipFIle
There is a small projet to demonstrate the bug.
Best regards,

Hi.
The code provided System.Zip2.pas is copyrighted code from Embarcadero. You should not be publishing their code, you should provide a patch file instead.
When decompressing a file larger than 4G and the progress is 4G Size, Position starts from the beginning. It is suspected that the bug in System.ZLib.pas exists in RAD11.
where can i find these files LzmaDec, LzmaEnc ??
I don't see LZMA2 in TZipCompression.
Is it supported ?
i want create a zip file in memory.
i do not want creat a real file.
