Hi,
I am working to compress files via seven zip sharp in c#.
I need to compress files with different extenuations (like .txt, *.abc, *.tff ,etc).
The flow work without exceptions, but the result is wrong.
In the 7z folder just the *.txt files exists.
Does anyone have a solation?

What I have tried:

var cmp = new SevenZipCompressor
			{
				ScanOnlyWritable = false,
				CompressionMode = Directory.Exists(@"C:\Users\User\Desktop\Zip.7z") ? SevenZip.CompressionMode.Append : SevenZip.CompressionMode.Create,
			};
									cmp.CompressFiles(@"C:\Users\User\Desktop\Zip.7z", "c:\\aaa\\file.abc");//this file don't exist in the output folder

What is the value of outputStringBuilder and CompressionMode and what is the expected output? Did you check the documentation to see that your usage is correct?

Compression mode is the way how to create the 7zip folder.
in our case to crate if it is not exist and update if the folder exist
outputStringBuilder is the output folder (I change it in the code bellow).
I expect to get a 7z folder with the file.abc.
actual the file is not exists.
BTW I try some extenuations of files and the only file that exist in the output folder is *.txt file is it related?

I know that, and that is not what I asked you. I asked you what are the values of those fields when you run the code, and are they consistent with the settings as shown in the documentation? You need to gather proper diagnostic information and show it in your question; we cannot guess what is going on.

As Richard MacCutchan implies it Looks like you did not read the docs.

/// Packs files into the archive.
// <param name="fileFullNames">Array of file names to pack.
// <param name="archiveName">The archive file name.
public void CompressFiles(string archiveName, params string[] fileFullNames)

I would say fileFullName does not accept something like "c:\xyz\*.xyz"

So which method could be used for this case?

Take care, I don't know the tool, but it Looks like you Need to build the SourceFileNameList by yourself. Have a look to this:

It is bad form to solicit points.

?Are you Aware, that it was related to the answer of OG?
I don't find here an answer from my side.

Doesn't matter, it's still bad form.

STOP NUKING ME and Play master of CP! It was only a hint for down vote @OriginalGriff!!!

I'm not 'nuking' you, and please do not shout. I merely tried to get you to follow the protocol, but you seem to take exception to any comment from me.

You have probably leased the truth for yourselves. And no, I think I tried to de- escalate, but for me it is you who are not able to follow. EOD.

Richard MacCutchan 24-Sep-17 12:28pm

Ha ha, if that is de-escalating I would hate to see you when you're angry. :)

You're missing something. Why are you using Directory.Exists on a file? I'm assuming "Zip.7z" is a file in your case.

That's not correct. Explorer treats .ZIP files as folders only for convenience to the user. They are still actual files, not folders, in applications.

Look here: Code 4 Freaks: Compress files using 7-Zip from C# code[^] it gives example code that is very similar to yours, but that doesn't pass a fixed string as the first parameter.
