Hi nudel,
Please bear with me as i try to explain - it's a bit complicated.
I want to be select x number of files and then give them a new, uniform name and at the same time numbers from 1 to x.
When the advanced rename dialog pops-up the name is preselected, just as in windows - i simply type the new name. Then comes the problem: if i check the sequential numbering box, only the first file gets the new name. The other files get the old name + number.
But if i choose the preset "number files", then only numbers are given, no new name. Now i have to aim precisely and select the stem of the filename in the "new name" box and give a new name... It's just unnecessarily fussy.
In windows explorer i just select the files, choose rename from the context menu and give a name and a number in () and windows automatically counts the number upwards and renames the files. (Although this is buggy in Vista, it does count only from 1 upwards).
There has to be a better way for this in DO. I suppose i'm to dense to see it
