This ensures that the correct inputs can be hashed to compare against the entry hash in the database. Another thing to note is that mapping files by scanning directories must be done on the same computer system in which the database was generated. It's not that common to see unless the database has been overwritten or truncated. When verifying entries, mismatched checksums will be displayed in red along with the correct value. The main menu will allow you to save entries, export entries to a CSV (comma-separated values) file, remove entries from the list (the database is not modified), hide 0 byte entries, verify CRC-64 header and data checksums, and map files to entry hashes.

Thumbcache Viewer allows you to extract thumbnail images from the thumbcache_*.db and iconcache_*.db database files found on Windows Vista, Windows 7, Windows 8, Windows 8.1, and Windows 10.
