How does wyUpdate know whether a file had been modified by the user?Answered
During an update patch, I understand that if wyUpdate sees that a file had been previously modified by the user, wyUpdate will skip this file for the patch.
How does wyUpdate check whether a file had been modified by the user? Are the “last modified date” and file size used for the verification? Or maybe a hash value is computed for each file for verification?
Answer
A hash of the file, as well as failure to apply a patch.
If the file isn't touched by an update, then wyUpdate doesn't care one way or another.
