File Verification

File verification is the process of checking that a file is complete, accurate, and unchanged from its original state. This is often done by generating a unique digital fingerprint, called a checksum or hash, using specialized software. When you verify the file, the software compares the current checksum to the original. If they match, the file is intact and unaltered; if not, it may be corrupted or tampered with. This process helps ensure data integrity, security, and that files are trustworthy before opening or using them.
