Here is what I am looking to do:
1. Upload .cab file
2. Once .cab file is uploaded run a process to extract the file using 7-zip
3. Once the file is extracted perform additional processing that is already coded.
The problem is once i start the upload 7-zip wants to run right away before the file is complete. The .cab files can range in size from 30MB all the way up to 200MB so I don't think a timer is the best option. Ideally there must be some way to have a confirmation the file is uploaded and a confirmation on when the cab is extracted.
