Tutorial using CI 8.0.0

[Newbie]

What does this mean:
Could not get file size of file temp000000001.dat_

Why do I get that.

Any reason for that.

What I can see is that I get that message NOT at the same place of compression.

Sorry, don't know how to explain.

Bat code:
echo off
:start
cls
set choice1=
set arc=
set retry=
echo.
set /p choice1=Please type game folder path (e.g. c:\Game):
if "%choice1%"=="" goto start
echo.
echo Creating archive files, please wait...
ata1
set arc=Data1.bin
arc a -ep1 -r -w.\ .\Disk1\%arc% -mprecomp:zl98:d1+srep+lzma:a1:mfbt4:d256m:fb128:mc 1000:lc8 "%choice1%\Data\*"
if ERRORLEVEL 1 goto arcfail
echo.All done.
pause
goto EOF
:arcfail
echo.
echo.WARNING: FreeArc returns an error in archive %arc%!
set /p retry=Do you wish to retry [Y/N]:
if /I "%retry%"=="Y" goto %arc:~0,5%
pause
:EOF


Thank You

EDIT:

Forgot to mention, it is while using Packjpg.dll compression.
