Hi,
Is there a way in which areas can be removed from a *.paint file
without converting the binary file to text and manually deleting the
entries?
Yes. There are two distinct options to choose from.
1) Based on border-drawing.
View the region of interest on a flat map.
Select Layers: Borders: Draw Borders
Enter the desired name for the new region, by typing it in or by
selecting from one of several available sources (area color, etc.)
Select Closed Border
Select Assign Paint Identifiers to nodes within border.
Select the paint column of interest.
Most likely, you will also want to select 'reassign nodes with' and
then choose the relevant paint column and paint name.
Then press the apply button and draw a border that completely
encompasses the region of interest. You don't have to hug the region,
so the border can be drawn very quickly.
Once the border is closed, the area of (dis)interest will be reassigned.
2) ROI-based: Select Surface: Region of Interest Operations:
Selection Method: Nodes within Paint.
Select the paint column of interest from Category and the area of
(dis)interest from the 'Select Name from List'
Press the Select Nodes button. You should see the relevant area or
domain turn green as all of its nodes are highlighted.
Select: Operate on Selected Nodes: Assign Paint Attributes to selected
Nodes.
Choose the same paint column of interest, then choose the paint name
you want the ROI reassigned to. (e.g., ??? for a default unassigned
status).
Press the Assign Paint button.

By either method, once you get what you want, be sure to save the
modified paint file, with the same or a different name, as appropriate.
As a general tip, it is generally advisable to make annotations in the
comment section for the particular column(s) that have changed, and
also in the main comment section for the paint file (e.g., who did what
and when).
Also, is there a way in which two *.paint files can be merged?
Yes, though it depends on exactly what you mean.
If you want to generate a composite paint file that includes various
columns that originated from different paint files, then use the append
options during file loading. Load one paint file, then open the other
one and select the append option. A menu will come up that allows you
to mix and match, from complete replacement to completely appending to
adding or replacing selected columns.
If you mean merging the areas/regions contained in one paint column
with those already existing in another, then this can also be done, one
area at a time, using variants of options 1 and 2 above.
