Yes. Please open the TreeSize File Search via the Windows "Start" menu or the TreeSize "File Search" menu, check the drives that should be searched, activate only the custom search type and adjust the date or days value. You may also use the Custom file search if you need more flexible filter options. After setting up the search options, hit the "Start" button. All listed files that are checked can then be moved using the "Move items". The file operations dialog will allow to specify the option to preserve the directory structure, as well as creating a log file of the operation.

Another possibility: Set a filter in the Options dialog of the main application. Then TreeSize will only include matching files when calculating the folder sizes. The results will provide a good overview of the distribution of these file type(s) and can be exported to a text file using the context menu.

Please go to "Tools > Options > Export", select your export type and activate the options "Include single files in export" and "Export the full directory branch" are activated.

Please make sure that the option "Tools > Options > Scan > General > Create statistics for file owner" is activated. Scan the folder in question. Go to the "Users" tab in the right pane, right-click on a user and select "Show files of this user". The list will be compiled and can be exported in various formats.
