Hello,

I want to rename all files in a folder (with subfolders) from \*.\* to \*.\*.deploy...for example from:

- test.dll

to

- test.dll.deploy

&nbsp;

and this for all files in a folder and the subfolders.

Thanks for an answer,

Peter

Hi Peter,

&nbsp;

You will need to define&nbsp;a Fileset&nbsp;and use the&nbsp;File Iterator to iterate over all the files in the directory, then use&nbsp;the "Rename&nbsp;File or&nbsp;Directory" action to rename the files. Attached is a sample project which demonstrates this.

&nbsp;

Regards,

Paul.
