I can batch rename and even start from a specific number
How can I rename in this way
10
20
30
40
or
5
10
15
20
or
2
4
6
8

some simple way to leave spaces so I can reorder
reordering a sequence with 115 moving between 112 & 113
111
112
113
114
115
yields
111
112
1135
113
114

for the first try krename

the 2nd sort of confuses me, guessing you could rename existing files and add spaces at the end though file trailing spaces at the end could be confusing/problematic or you could add "00" at the end instead of spaces

the 2nd example is an actual example, the method is not intuitive
00 yields the two zeros before the actual number
how would I get them at the tail end?

Is that a different tool than dolphin?

I figured out a method for dolphin
select all>right click>rename, brings a pop up
using #### sets the number of digits adding ####0 a trailing zero does the rename in multiples of ten, two trailing zeros would be multiple of 100
thanks for your help

that looks like fun & contained in the Mageia repositories

Thanks
