How to split a single word separated by space form single column into two columns

I am having the following records in column A

Column A

4.0K 0000000.png
4.0K 0004.png
32K 00(1).gif
16K 001.gif

My need is to split the size and name of the image in two different columns. That is

Column A    Column B

4.0K        0000000.png
4.0K        0004.png
32K         00(1).gif
16K         001.gif

How can I do this using Openoffice Calc.Version is 2.3?

How do I split text by Space in Excel?

Select the text you wish to split, and then click on the Data menu > Split text to columns. Select the Space. Your text will be split into columns.

Beginning with OOo 2.4, you could use the "text to columns" functionality to achieve this. There's a nice tutorial with screenshots how to apply it. If upgrading isn't a viable option for you, there are some other methods described (mainly using the csv import options).

EDIT: The blog post i've linked to points to some macros for splitting text on multiple columns. This would be an option for OOo 2.3 and prior.
