Testing archive: C.\Input2\WordDoc.docxĮRROR: Data Error : word\embeddings\oleObject2. How ever 7za.exe shows the following error if I try to open it via CMD: pdf file both files can be opend without any issues by using Word or Acrobat Reader DC. I want to open this file with 7.zip by using the following command:Ĭ:\Users\UserXY.\7z1604-extra\7za.exe t "C:\Users\UserXY.\Input2" -r pdf file which I am able to open with Acrobat Reader DC. This is a so-called split archive and 7ZIP should actually. the archive will have the same container info which is: you can extract and test the archive with 7zip but there are no filename information) 7ZIP Cannot open file as archive ErrorYou are not the only one having problems with this. Setting the properties to the following do the same job at 3.91 sec (i.a. Using the property values in the code-example "as is" will have a HUGE negative impact on performance, it takes 14.16 sec. Some additional test-info on code using a 17.9MB textfile.

The previous example was never going to decompress because it never wrote the required property information to the start of the file. exe file (executable NOT readable), you have to right click it, look down for 7-Zip and then click open archive, you then can view the contents of. It will write, and read, standard 7zip files as created by the Windows 7zip application. Here's a complete working example using the SevenZip SDK in C#. SharpZipLib - According to their FAQ, SharpZipLib doesn't support 7zip.CodeProject C# (.NET) Interface for 7-Zip Archive DLLs - only supports extracting from 7zip archives.Any working code examples that demonstrate creating a 7zip archive that is able to be extracted by the regular 7zip program? 7Zip SDK aka LZMA SDK - I guess I'm not smart enough to figure out how to use this (which is why I posted here).I referenced the project from my app, and it successfully created some archive files, but I was unable to extract the files using the regular 7-Zip program ( File.7z is not supported archive). 7zSharp Wrapper (found on CodePlex) - this wraps the 7z exe/ LZMA SDK.When I write the byte array to a file, I can't extract it using 7-Zip ( File.7z is not supported archive). The wrapper methods (wrapping the LZMA SDK) return type byte. 7Zip in memory compression - this refers to compressing cookies "in-memory" before sending to the client this method seems somewhat promising.As workmad3 mentions, I just need to guarantee that 7z.exe is installed on all target machines, which is something I can guarantee. "Shelling out" to 7z.exe - this is the simplest and most effective approach, and I can confirm that it works nicely.Here are my results with the examples provided as answers to this question How can I create 7-Zip archives from my C# console application? I need to be able to extract the archives using the regular, widely available 7-Zip program.
