In order to work on one of our project needs, we need to decompress zip file of size upto 100 GB. Could you please specify, can Aspose.zip decompress/ operate on such large files or could you please specify the maximum possible readable compressed file size?
Aspose.ZIP does not has any file size limitation. Please note that if you decompress/compress huge size documents, more memory would be required.
We do not have any restrictions on file size. We have tested files up to 10 GB some time ago and the process ran smoothly.
However, we will test such a huge files in various cases and let you know about time, memory and any concerns if happen as soon as possible.
It is to update you that most of our tests on huge archives went well but we have found a bug i.e. the extraction of huge .zip archive currently fails only if there are several entries and compressed size of first entry is above 4 GB. We will fix this issue in future releases of Aspose.ZIP for .NET API. The ID of this issue is ZIPNET-392. We will further look into the details of this problem and will keep you updated on the status of linked issue. We apologize for any inconvenience.
Thanks for the update.
While I am trying to read a zip file of size 17 GB, I receive this error message: ‘Signature of local file header does not match’. I have checked this file is not corrupt and I am able to decompress this file using 7z utility.
Thanks for the additional information. This is exactly what we have fixed as per linked issue ZIPNET-392. We will inform you via this thread as soon as next release of Aspose.ZIP for .NET containing the fix of ZIPNET-392 will be released within next couple of weeks.
