Zipping Excel files
If I zip up an Excel file of 7,115,716 bytes, the resulting zip file is
1,206,499 bytes, a reduction of 83%. If I do the same with an Excel file of 25,063,936 bytes, the zip file is 23,762,662, a reduction of only 5%. Does anyone know why this is?

could be anything: - embedded objects - wrong used range in the first sheet - number of filles cells/formulas So very difficult to give you a specific answer without knowing more about your two files -- Regards Frank Kabel Frankfurt, Germany "Brian" schrieb im Newsbeitrag ...

Hi Brian
Maybe your other file have protected sheets. If you zip a file with protected sheets it will not reduce the size much -- Regards Ron de Bruin http://www.rondebruin.nl "Brian" wrote in message ...

Brian
Depends on what is contained in the file. Text will compress quite a lot, graphics/objects not very much. For info on file compression visit....... http://www.howstuffworks.com/file-compression.htm Gord Dibben Excel MVP On Fri, 20 Aug 2004 17:44:22 +0100, "Brian" wrote: Hi Ron, No, there are no protected sheets.
