How to check archive file is valid before extract? #15

And how to determine archive file format, such as a .rar file is RAR or RAR5?

rikyoz commented 6 years ago

Checking if an archive is valid In the new version v3.0.0, you can use the BitExtractor::test method, which tests the input archive without extracting it and throws a BitException if it is not valid. Earlier versions of bit7z (<=2.1) do not support archive testing.

Determining the archive file format See issue #16
