Support RAR, RAR5 Formats and multi-volume/part archive files for zip, 7zip

Any planning for supporting rar, rar5 file processing? If yes, when we can expect the support for those files?
Also, does Aspose support multi-volume archive files for zip, 7zip?

Thanks for your interest in Aspose.ZIP for .NET API. We have logged the following new feature requests in our issue tracking system.

ZIPNET-436: Support RAR File Format Processing
ZIPNET-437: Support RAR5 File Format Processing
ZIPNET-438: Support multi-volume multi-part archive files for zip, 7zip

We will further look into the details of these problems and will keep you updated on the status of linked issues. We apologize for any inconvenience.


Regarding ZIPNET-436, it is to update you that we have rather vague plans to implement RAR extraction in mid or late 2020. But, we are not sure at the moment whether it will be just RAR or RAR5 format.

Please note that the RAR license does not allow to implement compression - only WinRAR software can create such archives, see, see 10th point.

So, if you are looking for a third party RAR compressor API, Aspose.ZIP will not provide RAR compression either. We will keep you posted on any further updates.

Aspose.ZIP for .NET 20.5 allows to extract RAR4 single-volume archives. RAR5 support expected later.

A post was split to a new topic: Protect RAR5 with Password and Support Decryption of Password Protected RAR5 using C# .NET

The following features have been implemented in the latest Aspose.ZIP release:
ZIPNET-436 : Support RAR File Format Processing
ZIPNET-437 : Support RAR5 File Format Processing
