Hi,

I may be missing some information regarding the TAB format, but I find quite inexplicable this behavior on file sizes:

 

After creating a couple of layers, and sent to different formats (SHP and TAB) I appreciated that some of the brand new layers have large differences on sizes when comparing with same layers from a past delivery.

Here are the figures from the 20th and 21st version of same layer:

Is there any explanation for this?

 

Thanks for your help!

Juanma,

 

 

In simple terms,

-SHP stores geometry

-TAB stores text attributes.

And what you have more in the data then has a larger size.
