losing modifications with update

[solargordon]

How can I update to the latest version without losing my modifications? I currently have a 4 column layout and it changes   when I update.

Thanks for the reply, some of my modifications are done in the actual ftp files though. I tried updating but they all got wiped out. so I had to revert back to an old backup I did before the update.

Yes it is wise to do as you say as updates will often change the core code.  So one has to 're-discoover' how to apply the patch.

@solargordon
In my spare time I am working on new layouts that use flex css to allow multi columns in a media dependent manner.  These will not need any core code changes.  In the meantime if you use a table based html for your layouts then that is easy to do but can run into trouble on different sized devices See

Also you could look at the 2 and 4 column Categories Layouts to use as a 'model' for a files layout
