rename existing files without overwrite the existing files

[hamad]

Hello everyone

I have a problem with multiple files ending with sequence like ~01 , 02. 03, 04, 05, 06 and 07 and so on . If i removed some files for example two files which ends with 03, 06 and 04.
now i want to rename all files again i used numbering option to add numbering at the suffix but the BRU telling me there is a file with the same name already exist. how to make BRU rename all files again with suffix 01 02 03 04 05 and so on
