If A Cell Meets A Condition, Copy That Row To Another Worksheet

We have a workbook that does not allow us to use the Move or Copy command. When we right click on the worksheet and select Move or Copy, we are able to check the box to make a copy, but when we click OK nothing happens.

We have checked to make sure that the workbook and worksheet:
1. Are not protected
2. That there are no hidden worksheets
3. That there are not worksheets that exist with the same name
4. That not all the worksheets are selected

There are only two worksheets in this workbook.

Any ideas of why we are unable to make a copy of this worksheet within the same workbook or to another workbook?

We have a large (4,000+ rows) excel worksheet from a prior employee that I
would like to be able to use, but it is password protected and no one has the
password. Is there a way to copy or save it as a different file that will
not copy the password protection? It would save me a couple days of work if
it is possible.
Thanks

Hi all.

I have set up a workbook that is sent out to lots of different users. They each keep and use their own copy.

I have set it up so that everything looks OK and is visible on MY screen, but I'm conscious that some users may have different screen sizes, different toolbars set up, and so on, which might make some parts not immediately visible to them.

I have set up an auto-execute macro which automatically sets the zoom factor to best fit, for several of the worksheets, and this works fine.
Here's the code that does it.
Code:

Sheets("WELCOME").Select
    Range("A1:N18").Select
    ActiveWindow.Zoom = True

By repeating this code for each worksheet, I can make each one be zoomed just right.

However, the file contains 8 sheets that are all identically laid out, except the number of rows is different.
What I want to do is go to the worksheet that has the largest number of rows (it's always the same worksheet, so I know which one it is), set the zoom factor for THAT worksheet (which I can do, and it always has the same number of rows), and then take THAT zoom factor, whatever it is - and it will vary depending on the user - and apply that to the other worksheets that have a similar layout.

I could just go through each worksheet and zoom it automatically, but that would mean that some of the sheets looked very large, others very small, and I'd like them to have a consistent appearance.
I could also specify a range on each worksheet that was similar to the appropriate range on the longest worksheet, and zoom that automatically, but that's not ideal either, because some of the row heights vary from sheet to sheet, and again I'll end up with different font sizes.

Anyone know how to do this ?

I have a large worksheet. Over 20,000 rows. I want to split every 900 rows into new worksheets. I need each worksheet to be 900 rows or less when done. Any macro would be helpful.

Still learning VBA - I am trying to delete an entire row based on a condition in one cell in the row. Typically I would just filter on that value and delete the rows, but I am not sure if that is a possibility in VBA code. Can you provide the code if not too complex.

Select Cell A1 if value is 100 delete entire row, else skip to next row. Then loop through each row in the spreadsheet till all rows with selected cell equal to 100 are deleted.
