d7zip's Issues
Very slow
This unit seems to be around ~50-60% slower than JEDI's implementation, maybe
you could look into that.
Original issue reported on code.google.com by hikaritokyo on 20 Sep 2014 at 1:01
SetProgressCallback shows insufficient space available if format is set to UDF
What steps will reproduce the problem?
1. I used your example shown at progdigy related to progressbar but instead of
7zip format I tried to uncompress an ISO image
with CreateInArchive(CLSID_CFormatUdf) do
begin
OpenFile('d:\myiso.iso'); //udf iso
SetProgressCallback(nil, ProgressCallback);
ExtractTo('e:\'); //a pendrive
end;
2. If progressbar is not used, then it works as expected.
3. BTW: program becomes unresponsive.
What is the expected output? What do you see instead?
Progressbar working, but I only see error.
What version of the product are you using? On what operating system?
1.2
Please provide any additional information below.
Thanks by advance. Great component. I'm using Delphi 7.

progressbar when creating file
when I create the file. zip
shows no progress and the application hangs
ex:
var
Arch: I7zOutArchive;
begin
Arch := CreateOutArchive(CLSID_CFormat7z);
Arch.AddFiles('C:\test', 'folder', '*.exe', true);
SetCompressionLevel(Arch, 5);
SevenZipSetCompressionMethod(Arch, m7BZip2);
Arch.SetProgressCallback(nil, ProgressCallback);//Here hangs the application
Arch.SaveToFile('c:\test.zip');
end;

T7zBatchItem Size property type not sufficient for large archives
An error occurs when working with large archives. The Cardinal type for the
stream size is not sufficient, Int64 fixes the problem.
var
Arch: I7zOutArchive;
Arch := CreateOutArchive(CLSID_CFormat7z);
Arch.AddStream(aStream, soReference, faArchive, CurrentFileTime,
CurrentFileTime, 'folder\test.bin', false, false);
-> error when aStream.Size > 4 GB

Unable to open bzip2 compressed files
What steps will reproduce the problem?
1. Tried to open a bzip2 archive created with 7zip. I have one item in the
archive, and i7z.NumberOfItems returns 1, but i7z.ItemPath[i] returns ''.
What version of the product are you using? On what operating system?
Using latest ver of code and tried 7z.dll included and latest (9.20).
