It's actually a very easy problem, but I'm just starting with Kix.

Other people from my departement have to do payments, for this they insert a floppydisk with the files in the computer.

copy a:\*.* c:\isabel\betalingen
cd\
cd isabel
cd betalingen
ren *.* *.fbf
cd\
cd backup
KIX32 SORTDATE.KIX

::SORTDATE.KIX
$sdate = substr( @date, 9, 2 ) + substr( @date, 6, 2 ) + substr( @date, 1, 4 )
md "$sdate"
cd "$sdate"

IF they start convert.bat a little program starts that copies the files, and then renames it, but the originals have to be backed up, not the altered files.

So it's basically just a problem on how to change a directory, and copy files from the floppydisk to my computer
