I am asking this question on behalf of a co-worker.

1) We have an 11 Gigabyte RAR (WinRAR) file.

2) When we try to uncompress the file we are getting a CRC (checksum) error.

3) We are using the latest version of WinRAR (3.4.2).

4) The WinRAR repair utility is not working on the file.

5) We are unable to extract the and keep it even if it is bad (WinRAR allows you to do this sometimes. Extract without confirmation does not work).

Any help will be appreciated.

A file of that size should have a rescue portion of 10 % (also called Recovery), if it was selected for this. In case it's not, you will have the possibility of extracting only until the error appears. At this point, you have 2 choices:

  1. Contact the author of the file and ask him to provide another file.

  2. Extract the files and when the error appears, don't close it. Instead navigate to the extraction directory and copy all the already extracted files, then close the message with the error.
