Siren: Infinite Ways To Rename And Organize Files

Siren (Version: 3.01) is a freeware file renamer, it features many ways to rename, move and copy files using expressions to create renaming rules.

The expressions can be any in number or combination and use almost any file attribute one can think of. One can change the case, remove parts of the file name, use file paths, extensions, audio file tags, modified dates, checksums and lots more. It can use and read attributes belonging to many audio, video, image and other kinds of files.

Siren works by loading a folder and checking off or selecting files to work on or alternatively work on all files and subdirectories. The next step would be to click on the right hand side of the Expression text field to add rules. The first (tag icon) presents all the options available, the second (magic wand icon) helps test and build expressions. When done the new file name(s) will be shown and one can click Rename (play icon) to rename the files. The Create copies (fast forward icon) button will create copies first then apply the rename rules.

The filter option at the top right lets the user filter visible files. Filters can be any combination of file types and regular expressions too. For example to filter down to “jpg”, “bmp” or files beginning with a letter use *.jpg;*.bmp;[A-Z]*

The Favourites menu lets the user save expressions or rules to re-use later. It is also possible to test the expressions and renaming rules with a “testbed” that is available under the ? menu, the same menu also includes Siren’s detailed help file which includes examples.

Siren has some command line support, works on Windows XP and newer and doesn’t require installation.
