Answer 1

Option 1
If you have Total Commander, go to the desired directory, open the search (Alt + F7), leave the search bar empty, go to the Advanced tab, check Find duplicate files, uncheck all sub-items, but check the same plugin fields , then:
- click on the plus button, select tc\name in the drop-down menu
- click on the plus button, select tc\ext in the drop-down menu , the line [=tc.name][=tc.ext] is
formed on the left in the field - in the second field, replace equal with "<>", get [=tc.name][<>tc.ext] - Click Start Search, the output will show files with the same name but different extensions.
F3 is working in search results. If you want more freedom in operations with the found files - click the Feed to listbox button on the right under the issue, the search results will open in a new panel.
- download and install the AllDup program .
- start. Remove the checkboxes from unnecessary drives / folders, click Add, select the path to the desired folder, OK. The desired folder will be added to the list of search locations.
Repeat as needed for multiple folders. If necessary, check / uncheck the boxes for searching in subdirectories.
- click on Search Criteria in the toolbar. Name should be checked, the rest should be unchecked.
- press the Start Search button in the toolbar, get the result. Process/save as needed.
