Hmm didn't even notice that.
That would explain why it can't copy the file

aellis - Can you post the first few lines from file_list.txt
Jeez, I need new glasses. I corrected the ini error in the parh statement.
Still no joy. Only this time error 0x05 showed up again.
First 5 lines of file_list.txt:
C:\Documents and Settings\Andrew\Desktop\PyFFI TestFolder\altarcloth01.nifC:\Documents and Settings\Andrew\Desktop\PyFFI TestFolder\anvilaltar01.nifC:\Documents and Settings\Andrew\Desktop\PyFFI TestFolder\anvilbasemantdoorframe01.nifC:\Documents and Settings\Andrew\Desktop\PyFFI TestFolder\anvilchaindollholder01.nifC:\Documents and Settings\Andrew\Desktop\PyFFI TestFolder\anvilcirclebench01.nif
It seemed to have barfed on the second file - anvilaltar01.nif.
files_skipped.txt and output_log.txt are still 0 bytes.
tmp_bat_a.bat has changed from the previous posting:
@echo PROC A 1C:cd C:\Program Files\python25\python.exe Scripts\niftoaster.py optimize --noninteractive "C:\Program Files\python25\temp_a.nif" > C:\Program Files\python25\tmp_a.log
I did not find a "tmp_a.log" in the python25 directory.
However, I did find a tmp_a.nif and a tmp_b.nif.
AFAIK, XP does not control Program Files with UAC as Vista does. I don't think that is where the problem lies.
Hmmm, I just had a thought. Wrye Bash is open. Maybe there is some issue with 2 python apps running at the same time? I'm going to close it and try again.
Nope. That wasn't it.
Edited to add addtional information
