Which method would NOT affect the verification of an evidence file in EnCase?

Reacquiring the evidence file does not affect the verification of the evidence because the process of reacquisition typically aims to create a new copy that is an exact duplicate of the original data. Verification in this context often involves generating and comparing hash values (such as MD5 or SHA-1) before and after the acquisition process to ensure that the integrity of the evidence remains intact. If the reacquisition process is performed correctly, the new file will retain the same hash value as the original, confirming that the data has not been altered in any way during the acquisition.

In contrast, changing the logical filename, moving the file to a different directory, or altering the compression settings can all potentially modify the file's metadata or the contents themselves, which can lead to a change in its hash value. Such changes would render the verification process invalid, as the original evidence would no longer match what was acquired. Therefore, reacquiring the evidence is essential for maintaining the chain of custody and ensuring the validity of the evidence in forensic investigations.
