In the Explorer window, select all files, right-click and select Rename. Windows will choose the start number as the number between parentheses, so write the file using a number that is 1 digit more than the number of digits required.
Example : We need the template "test_xxx". Using File Explorer, rename the files to "tes (1000)". Now your files will be called ["tes (1000)", "tes (1001)", "tes (1002)", etc.]. Hold SHIFT and right-click in an open area of ββExplorer, then select "Open Command Window Here." Run the following command:
ren *.* test_???.*
This will rename all files to the appropriate format ["test_000", "test_001", "test_002", etc.].
