Then enter a numerical value for the file size. The default unit used for the file size is
bytes. Optionally, you can change the unit to either KB, MB, or GB.
Click the file properties button to obtain the file's current size. This current value populate
the file size value field and is used to set the file size threshold. The File size option must
be selected for the file properties button to appear.
Last modified date is. Select this option make the monitor dependent on the date on
which the file is last modified. This field is populated using the file properties button;
click this button to populate the field with the most recent date and time on which
the file was modified. This option must be selected for the file properties button to
appear.
File checksum using ____ is _____. Select this option to make the monitor
dependent on the file's checksum. Select the option, then select the algorithm (SHA1,
SHA224, SHA256, SHA384, SHA512) WhatsUp Goldl uses to calculate the checksum.
This field is populated using the file properties button; click this button to populate
the field with the file's current checksum. This option must be selected for the file
properties button to appear.
Warning: Selecting this option can greatly increase the amount of time it takes to complete
the monitor scan and can possibly have an adverse affect on WhatsUp Gold performance.
The probability of lengthy monitor scans and slower performance increases when you use
algorithms other than SHA1 when you are scanning large files, or when you scan files
located on network shares.

xv) About file checksum
File checksums are fingerprint-like fixed data strings assigned to files when they are saved.
Checksum algorithms, such as SHA1 and SHA512, are used to monitor checksum files to
detect accidental modification of a file, such as corruption during the storage or transmission
process. These algorithms match checksums against each other to look for discrepancies; if
any exist, the file is known to have been modified.
The File Properties Monitor can monitor current checksum for a file to ensure that it has not
been modified by matching the checksum specified in the monitor-configuration to the
current checksum. If the monitor finds mismatched checksums, the file is corrupted.
