A May 2017 Microsft security update for Windows 10 conflicted with a major routine in FileBoss resulting in FileBoss not starting on some Windows 10 systems.
Versions V3.101 and later, fix the problem. You can read more about this at the page
Windows Creators Conflict.
Duplicates can be found in one folder, multiple folders or paths and even across network drives.
If you are looking for duplicate files in a single folder then display that folder in an Explorer tab and start with Step #2 below.
However if you want to search for duplicates across multiple folders start with Step #1 which is next.
If you want to search across multiple folders or drives, create a Virtual Folder of those folders first and then check for duplicates. Creating a Virtual Folder first makes the process quick, easy to repeat and easy to refine. In addition all of the normal file manipulation routines are available while reviewing the duplicate files.

Review the settings
Hint: If too many files are displayed you can either perform the operation again redefining what makes a duplicate a duplicate or which files should be included in the evaluation. Or you can select whole groups of files and hide (click the Hide Selected Files button) and then examine what is left.
