Folder Splitter can split one large folder into several smaller ones.


  • Define the Maximum Size of the Destination Folders. (useful if you want to backup the folders to CDs/DVDs)
  • Decide, whether to move or copy the files to their new destination.
  • Choose between the option to keep the files in their alphabetical order or to minimize the number of required Destination Folders.
  • Include a Log File with every new folder.
  • "Folder UnSplit": Combine the splitted folders to a new single folder. (Reverse the Splitting process.)

What's New

Version 0.9b10:
  • Fixes a StackOverflow for deep folder hierarchies.
  • Sorting is now numerical.
  • LogFile shoould now handle unicode characters better.
  • Folder Splitter's very first step is to count all the source items. This is now reflected in the status bars (instead of Folder Splitter just being unresponsive.)

Tried 'Big Mean Folder Machine" before finding this little app. And now I'm amazed at this small, spiffy, light and very well-written piece of code.
"Folder Splitter" no-frills, no complicated settings are an invitation to keep it like one of your favorites tools.
I use it every week and until now see no problem or hassle whatsoever.
The only 'catch' is that you HAVE to create a new folder (with an indifferent name) just to be the target of the splitted folders - it strangely cannot split within the same directory (the same folder that contains the original big folder).
Aside from that, this is a program that relies on your Mac's processing and HD speeds and quite useful.
It delivers what it promises. Did I mention it is fast?

What number should I enter into the size in Megabytes if I want to burn to DVD?

Here are some tips from a speed-demon:
When splitting for burning, remember, you must leave the tail end of the disc space for format information (this is up to 1gb of data). Here are some specs for this:
disc folder size
cd about 650mb
dvd(standard) about 3.9gb-4gb
dvd5 about 7gb
dvdDL(doublelayer) about 7.9-8gb
hddvd(standard) about 19gb-24gb
bluray(SL) about 24gb
bluray(DL) about 49gb
any disc with higher than 50gb space requires 2gb cushion on mac
final note:
Mac like to burn CONTIGUOUS data. If your HDD is cluttered like mine, an old 80gb external is cheap; wipe it, format it with GUID and extended journaling, use your favorite burning software and set up the external as your temp storage drive. This will maintain contiguous data for a fast, reliable burn without filepermission problems(just in case you have any on your internal HDD, moving a copy to external removes the limitations as externals do not have any permissions; check with get info and make sure that the setting shows to ignore file permissions on the volume). I hope this helps. Any questions, check my profile and find my email address, you can then put "Macupdate question" in subject, it will help sort. Good day.

A fantastic free alternative to the expensive CD Folder Partitioner. This app has more functionality, too!

Extremely usefull little app.
As a feature request, it definitely needs a "preview" button so you can check what will be done before you do it for real...

I used it shortly for splitting 8 GB into to two folders for burning - it did it flawlessly.

I then tried with my home folder so I could have a backup and it did had some problems with special characters - nonetheless, it has a bright bright future.

Considering others are asking $40 for basically the same thing (http://www.macupdate.com/info.php/id/22687) I think this is an amazing tool.

This is a really handy program. I've had no problems with it. The developer is very responsive to requests. Plus it's free. You can't ask for more.
