I just created several folder within folders, closed WinMail and reopened
WinMail and all folder trees were collapsed.
I suggest a heirarchy of folder trees to reduce the number or to rethink the
need for that many subfolders. I don't use WinMail but Office Outlook. I
have a major folder for Individuals, within that I have approximately 25
individuals. I have another major folder for Computer Club, with folders of
catagories, such as Newsletter info, minutes (I maintain the web site). Then
another major folder for Foundation ( non-profit), again folders of Minutes,
Word documents, Excel spreadsheets, financial statements, etc. I find that
this allows for a much shorter list. Office Outlook opens with the folder
tree exactly as when closed.
