The Duplicate Files report locates and lists duplicate files throughout the scanned folder (and its sub-folders).
How duplicate files are identified depends upon the Compare drop-down box setting. You can elect to compare files by name alone, a combination of name and file size, or a combination of the name, size, and date. There are also options that allow file name comparisons to ignore special and/or numeric characters. For example, when ignoring special and numeric characters, the file name "test.xml" would match "test.xml".
Once the Duplicate Files report has been generated, duplicate files are displayed in groups.
As with all File Reports, the Duplicate Files report can be sorted by any column in either ascending or descending order. Simply click a column header to sort by that column – click again to reverse the sort order.
The Selection Assist button makes it easier to select multiple duplicate file records for processing (e.g. moving, deleting, etc.).
With this tool, you can either select all but the first duplicate in each group (leaving only the first unselected) - or you can do the reverse (select all but the last duplicate in each group).
Note that selection assistance features can be combined with sorting to achieve different goals. For example, if you're comparing files by name and size you can sort the duplicate files report by the Modified date/time column and then use the Selection Assist button to effectively mark the oldest/newest entries (depending on the current sort direction) in each duplicate group.
Important: Always review your duplicate file selections carefully (to ensure correctness) before using file processing functions.
The Duplicate Files report has the ability to ignore files smaller than a specific threshold, which defaults to 100Kb. Setting this threshold to a higher value increases the speed of File Report scans, and reduces system memory utilization. You can also set this option to "all files" to ensure that no file is omitted.
The Duplicate Files report can be exported to a wide range of file formats.
You can print the Duplicate Files Report by using the Print button at the bottom of the report generator window. The list will print as it appears in the report (e.g. in the current sorted order, etc).
