DEFRAGMENT, VOLUME, Qualifiers, /EXCLUDE
*Conan The Librarian
/EXCLUDE=(file-spec[,...]) /NOEXCLUDE (default) The /EXCLUDE qualifier specifies files to be excluded from processing. The defragmentation process ignores files matching the listed file specifications. Any file indicated in the EXCLUDE list and in either the FREQUENT or DORMANT lists is excluded from processing. NOTE The defragmentation process always excludes system files, open files, files excluded in an options file (/OPTIONS qualifier), and files excluded using the /IGNORE qualifier.
