Hi Darwin, thanks for the welcome
As the developer it's always a bit of a challenge to ask questions on the own software without sounding defensive (hope I wasn't). I value any honest feedback I receive as this is the only way for me to know what needs to be improved.
On the number of found files, did you check under Options - Exclusions whether Exclude hidden/system files/folders was selected? Does it make any difference if you deselect those options? (if they were selected in the first place)
On the search speed, by default LookDisk searches inside archives (zip, cab, rar etc) and that could explain why it was considerably slower. If you deselect the searches in archives (under Options), does it make a difference in terms of search speed?
Glad to hear the positive comments on the UI and duplicate file finding.
Thanks again for the additional feedback.
Cheers,
Vincenzo
