Re: Increment number in filename

Hi eloderma,

The are two different ways of doing it, I'll explain one... You can't rename directly, because you'll be trying to rename to already existing names, i.e. renaming 1.pdf to 2.pdf, while 2.pdf already exists - you have to do it 2 renaming steps.

Step 1)
* Insert "_" as Prefix;
* Rename, you'll have something like this: _1.pdf, _2.pdf, etc.

Step 2)
* Sort Numerically, so you have: from _1.pdf to _N.pdf appearing in order;
* Delete from position 1 to the end of the file (skip extension);
* Serialize Incremental, index starts at 2, step 1, as prefix;
* Rename, and it's done!
