My W7 machine crashed and killed my boot drive, taking my Tixati config with it. I rebuilt in W10 now have over 300GB of preallocated files that are incomplete (discrepancy between "size" and "size on disk"). Is there an easy way to identify the incomplete files so they can be disposed of, short of manual sorting?

if you were using the 'incomplete file name format' option you could look for files with the incomplete tag.

or if you had separate download and complete folders you'd only have complete items in the complete folder.
