Created Unassigned: While compressing directory using 7z.dll in c# the first charecter is missing [12643]

I am using the below code to compress the directory.

__var sevenZipArchive = new SevenZipCompress();
SevenZipBase.SetLibraryPath(@"7z.dll");
sevenZipArchive.CompressDirectory(DirectoryName, archiveFileName);__

The directory which I have given for compression contains JBD Direcoty (it has lot of sub directories inside in it) & export.mdb file.

When I look at the compressed file after performing the operation the entries in the archive file BD & xport.mdb (the first charecter is missing).

Does any body faced the same problem. Please help me.

Created Unassigned: extraction issue [12651]

Hi,

I am using SevenZipSharp to decompress a RAR archive and even though I set the "PreserveDirectoryStructure" flag to False, the folder(s) get extracted as empty folders.

For example, if this is my Archive File:

Archive.rar
|
--- Folder1 > File1, File2
|
--- Folder2 > FileA, FileB

and then I look at the extracted contents I have this:

Folder1
Folder2
File1
File2
FileA
FileB

So, it doesn't preserve the directory structure, but it still extracts empty folders. Why extract empty folders if you do not want to preserve the directory structure?? It doesn't make sense. Anyway, is there any additional flag or something I am missing so this doesn't happen?

Thanks in advance!

benxbenx has uploaded a patch.

Description:
the patch is releated to split archives (7z.001, 7z.002 ...):
(i use latest source und 7z.dll 9.20)

----------------------------------------------
Patch 1 - MultiStreamWrapper.Seek
i have had a big split archive an the caller (7z.dll) called Seek with SeekOrigin.End and Offset=-500 during extraction -> Exception
(there is another maybe wrong seek-Implementation here in ArchiveEmulationStreamProxy that has to be fixed?)
----------------------------------------------
Patch 2 - Initialization/Dispose-Problem
when i use

using (var extractor = new SevenZipExtractor(srcZipFile){
...
}

to extract split archive 2 got 2 nullref-Exceptions. The line
private ReadOnlyCollection<string> _volumeFileNames = new ReadOnlyCollection<string>(new List<string>());

is not a very good patch but the initialization and use of _volumeFileNames seems to be a litte bit blurry.

Rated 4 Stars (out of 5) - The Release is good and stable, but we had some huge performance problems in our application. my proposal would be to remove the GC.Collect call in Method SetOperationResult(OperationResult operationResult) in class ArchiveUpdateCallback.cs. In our application it gets a speedup of factor 400. maybe others could also benefit of that. i am not really sure that you have to call manually GC.Collect here.

Hi guys.
I've run into this kind of issue, the last days, and it took me quite a while to find a solution.
Even if it's not a perfect one.

I had to add this line to my code
ConfigurationManager.AppSettings["7zLocation"] = sevenZipPath;

I went here after reading the source code of SevenZipSharp and I found this line:

__

internal static class SevenZipLibraryManager
...
    private static string _libraryFileName = ConfigurationManager.AppSettings["7zLocation"] ??
        Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location), "7z.dll");
__


Without the previous line the code was blowing with an exception of invalid path when I called the method bellow.
I can assure you that the path is a perfect valid path, I've a lot of verifications before calling this line, and If I get a bad path I must throw an exception . . .

SevenZipBase.SetLibraryPath(sevenZipPath);

From your experience do you have any ideas of other workaround ? Is it related to how I'm referencing the DLL ?
Thanks in advance for your help.

I have tried to integrate your SevenZipSharp library into my windows service and I have a lot of trouble related to threading.

When I use the library in a single thread environment, it work perfectly. As soon as I try to use it with thread ( using TPL in C# 4 ), it start to failed all over the place.

So, I return back to you Test Program and use the Multi-threaded extraction test examples that you give. Running it a couple of times, and it also failed.

Example of error that occurs are :
On this line :
using (var tmp = new SevenZipExtractor(@"D:\AutomatedBuild\LotOfFiles_2.zip")) Error : {"An item with the same key has already been added."}

Does this project continue to be alive or is now dead ? I don't see a lot of activity in it. Does anybody have idea to help me use this library, I need this fast, otherwise I will switch to something else. But this one was good... I need extraction of both zip and rar and 7z. And not a lot of library do this.

New Post: 7zip RDB support?

Hi all.

I've used 7zip to extract the contents of a .RDB files. When I do so, it creates a folder with a number of files in it. It's strange, since RDB isn't necessarily a compressed file, but 7zip knows what to do with it and how to decompress it.

My question is, how do I do this with SevenZipSharp? What is 7zip doing to the RDB files to extract it? Is it treating it like another file format?

I've tried running the 7zip command line version on the file and it won't work either, so I'm wondering what voodoo the program is doing that's allowing it to do this.

SevenZipSharp newest release was actually a number of years ago. If you read the correspondence you will eventually realize that there has been no new development for this library for several years. The fellow who wrote this library has apparently lost interest. I wrote him several times on matters he should have been happy to respond to, but he did not reply.

Thus, understand that the fellow who developed this library is not working in association with the fellow who is maintaining and at times adding new features to 7Zip. No one here will be able to answer your question because they have not been active with this product for several years. That being said, this library is a safe library to use for compressing and unzipping archives. If you try to do something such as RDB with SevenZipSharp, it may work for you. But you must be realistic. Without anyone running this project any more, be prepared to be disappointed.

Sincerely,

Pastor Burt

In answer to your question, yes, the library had or has considerable potential. I am using it myself but ran into a number of roadblocks where features that should have been there and even that were claimed to be there, were not there. Consequently, I then decided to use DotNetZip, and found once again some problems and it too appears to no longer be really supported either. Subsequently, for my project I am now using actually BOTH libraries, but in a more limited way then I would have like were either of these products still being supported - which they are not. You will find that you will be able to do the necessary things, but beyond that be prepared to write a lot of code yourself.

Pastor Burt

A big thank you Pastor Burt to have answer my question !

I am currently using SharpZipLib which work pretty well actually. But it only support .zip file, not rar files.

Unfortunately I am not in a position to use a library that is no more supported. I am sorry to see that SevenZipSharp is no more supported, since it was able to support more type of compression, which I need. But without support, it's not an option. I will probably go with the command-line 7zip directly for the rar file.


Thanks for your information !

I also too have the Sharp Library but am withdrawing it. It TOO is no longer supported by anyone. Using command line is a good option, but I need more functionality. SevenZipLib is ok, to be used sparingly. My hope is that it does not go completely South by the time Windows 9 comes out. Then I will be screwed. Let me be clear about this. That fellow who use to behind the SevenZipLib did not respond to me. Thus, I decided to respond truthfully to you. Now if he doesn't like that or doesn't want to have his product labeled as DEAD, then he is going to have to in writing come out and contradict what I wrote. In other words, he no longer can ignore those of us who otherwise wish to use his library. If he doesn't reply - which I think he won't - then the product is exactly as I described to you - no longer supported.

Hey guys, ive got 2 odd issues.

First one is that if I set the compression format to zip, I cannot set the compression method to PPMD, it just jumps to default.

Another Issue is that when I set encryption to AES and method to LZMA, the library will crash the program.

I really need help on this.
Ive replaced the 7z.dll, first with the one provided here and also with the latest on on 7zip.

Ive fixed the PPMD issue, ive just took out the case statement in the IsValid Function in the Compressor class.

Dear HockeyMTI555: I am emailing you to now thank you. I have been working on a zipping program for some time. I have tried many approaches or libraries looking for the best. I thought I had the BEST approach at last defined and was hopeful development could go forward with more results and a solid blueprint for completion. You email and decision to go to "/command-line 7zip directly for the rar file/" caused me to pause. I was not attracted to this, so I had not tried this approach. But the more I considered your response, I came to conclude that possibly it would be a workable solution. Consequently, I tried it and was quite satisfied. You were right, and I am pleased with the result. Consequently, I too am abandoning both SevenZipSharp and DotNetLib. There were so many things wrong with SevenZipSharp that forced me to compromise, I just was not happy with it. So far the direct 7Zip approach has been able to succeed where SevenZipSharp failed. The DotNetLib approach did work well, but it was limited only to Zip and nothing else. The Command Line approach, which I have tested, has the ability to have a unified approach that will work with a variety of the archives, and this I like. Thank you for your response as well. It caused me to second guess my conclusions and this time the results appear to be very positive. I very much appreciate your second set of eyes.

Rated 5 Stars (out of 5) - Hi. I have been programming for over 40 years. Thus, I speak as an authority. When I started with this library I gave it an excellent rating. However, after two months of working with it every day, I have to remove that rating. There is simply too many things in this library that just DON’T WORK. Moreover, the library is not supported at all. The last release was 4.5 years ago. The author of the library has lost all interest in this library and does not respond to anything concerning it. I also tried DotNetZip, and found that it too simply was no longer supported at all. Finally at the advice of others, I began to integrate 7z.exe directly through the command line integrated into my .Net WinForm development. Everything worked and worked well. Moreover, 7z.exe is being aggressively supported. The last release was in December, 2013, and the author has been supporting the product faithfully now for years. You can and should integrate 7z.exe into your Windows applications, and nothing else. Sincerely, Pastor Burt.
