Error on decompressing 7z or zip archive

Jun 9, 2015 at 2:08 PM
Hi all, i'm trying to decompress .7z or .zip (Multiple Volume) using this library. My test archives has been compressed with the 7-zip tool. Unfortunately all my efforts did not work, instead i get an Excepiton. Reviewing the source code i guess i could idenitfiy the error at SevenZipExtractor.cs Line 577. Watch the code sample below please.
In case of decompressing a 7z or zip files the extension of the files are '.001' and the this._volumeFileNames is null.
I would be grateful if anybody has a solution how i could decompress such multiple volume archive.
Thank you for your attention and your help.

if (!this._fileName.EndsWith(".001", StringComparison.OrdinalIgnoreCase) || _(this._volumeFileNames.Count == 1))_
