Files compressed as folders?

Jul 3, 2009 at 4:31 AM

Hey, I'm getting mindblown by this. I'm compressing a file (i.e. myfile.txt), and after compressing it I obtain my 7zip file. However, when I open it instead of a myfile.txt as a text file, I find a folder named myfile.txt.

This is the compressing code:

SevenZipCompressor szc = new SevenZipCompressor();
szc.CompressFiles(tmpDir, outFile, OutArchiveFormat.SevenZip);

Where tmpDir is the array with the content to be compressed (in this case, C:\test\myfile.txt) and outFile is the path to the 7z file (C:\test\compressed.7z).

Any help sorting this out will be greatly appreciated!

Hey, you use the old version of SevenZipSharp! Upgrade to the 0.51 version or download the most recent svn checkout.

Thanks for the quick reply.

Ok I'm using 0.51, but it's still doing the same thing.


This is what the compressing line has become:

szc.CompressFiles(tmpDir, outFile);

All I want to do is compress files, one per 7z file. Am I doing something wrong?

Try the new, much improved 0.52 release. To compress a file, you code like

szc.CompressFiles("path to my new archive", "path to my first file", "path to my second file, etc.");

I tried that, same output...

Here's a screenshot of what's going on

this is ridiculos, i tested that kind of compression. Seems to wrongly determine file attributes. Please send a copy of such buggy archive to on my email gmarkhor at

ah, and please write the version of 7z.dll you use and winrar

I fixed it. The mistake was that it was not adding a backslash to the path (so it was something like c:\testmyfile.txt, and it read that as a folder...).

Thanks for all your help, and I'm very sorry for taking your time.
