You wont be able to get them back, you could copy them in if you had a copy of the original formates through.

No, not a new name, just open (without enabling macros), save, then close. You don’t need to make *any* changes to the file.

Yes halving is possible for some files.

As I understand it an early definition of the microsoft office standard for documents used to include a copy of the previous document within the next saved version.

So save a document as a new name = original size, then mod the document and save again. Now both versions are saved within the current document! Double the size! As good an idea as dlls right!

This approach was originally to give you recourse if your current version became corrupted. Somehow you could extract the previous version, ie prior to the corruption.
Something like an undo after save option.

It seems to be inconsistently applied now but I used to find Arena documents, *.doe files were in this format and could be halved by saving under a new name. Arena is a discrete event simulation graphical programming environment now sold by Rockwell.
