Basic settings can be changed by clicking the Settings button at the bottom of the ExactFile application window.
Number of threads to use for computing checksums.
Leave this as “Default” to allow ExactFile to choose how many threads to use when creating checksums. Unless specified otherwise, ExactFile will use as many hashing threads as there are CPU cores on your computer. You may specify a maximum of 16 threads.
Use only one thread on written CD media
This should be selected unless you have a specific reason to disable it. When reading from written CD media, using multiple threads is inefficient because of the slow access time of optical media.
Here you can set the font used when showing reports (digest test results, etc). Fixed-width fonts tend to work best.
