Use this parameter to specify the maximum top-level container file size that the decomposer can process. The decomposer does not process any top-level container file of size equal to or greater than the value that you specify in Symantec Protection Engine. The DecFileSize parameter accepts a value in GB. The maximum top-level container file size that you can specify in Symantec Protection Engine for tar, rar, and zip containers is 30GB (approximately 30719 MB). For other containers, you can specify a maximum top-level container file size of 2 GB (approximately 1907 MB).
For example, If you specify 20 GB as the maximum limit, then the decomposer processes a top-level container file of type tar/rar/zip of size less than 20 GB. For any other top-level container file type, the limit is still 2 GB.
