The compression has failed for an unknown reason with code -2147024882

description

Hi all,

Iam using 7z.dll of 9.20 version. I am able to generate compressed files of small size. While generating compressed file for large files I am getting "The compression has failed for an unknown reason with code -2147024882" error. total folder size iam trying to compress is 36MB which is having 28MB file to be compressed along with other files (Thats why iam unable to attach the files here). We are having Callback methods to check the error codes received from 7z.dll, there we are getting this message and error code. Please help me on this issue.

Thanks,
R. Durga Prasad.
