Yes, it's a very interesting bug that I'm currently investigating. May 
be I don't use the temp directory correctly.
When making the output, I start by copying the template file to another 
filename/filepath.
When I use my code to generate the new filename in the temp directory 
(Nom:= OD_Temporaire.Nouveau_ODT(Prefixe);),
on the second time, the system doesn't find the source file for the copy 
('FileVirtualTree_txt_to_odt.odt') and the copy fails.
But the source file isn't deleted, it continues to be visible in File 
Explorer, you can open it in LibreOffice.
And this happens either if , instead of using the CopyFile from 
lazutils/FileUtils.pas,  I use a home made "MyCopyFile" function coded 
with BlockRead/BlockWrite or even using command line cmd.exe / xcopy to 
do the job.

But if I copy the template to a file in the exe directory (just Nom:= 
'temp_'+IntToStr(temp)+'.odt'; Inc(temp);), it works ...

I didn't had time to work on this for now. I think it's a bit too much 
complicated for FormatDateTime, it would be safer to decode the datetime 
value in a special function (something like days:= int(datetime); 
hours:= frac(datetime)*24; minutes:= frac(hours)*60 ... )
