i think the var-directory is a good place for those 'temporary' files.
The errormessage probably comes from your .htaccess file which restricts the access to files in the var-folder except for pdfs and images. Perhaps you should post the complete errormessage, try copy'n'paste :-)
If the error is invoked by .htaccess restrictions, edit that file. You can find it in the ezpublish main directory. Find the following lines and add your csv-files to it:
from:
<FilesMatch "(^index\.php|favicon\.ico|index_treemenu\.php|\.(gif|jpe?g?|png|css|js|swf|html?)|var(.+)storage.pdf(.+)\.pdf)$">
to: <FilesMatch "(^index\.php|favicon\.ico|index_treemenu\.php|\.(gif|jpe?g?|png|css|js|swf|html?)|var(.+)storage.pdf(.+)\.pdf|var(.+)\.csv)$">
from:
RewriteRule !(\.(gif|jpe?g?|png|css|js|swf|html?)|var(.+)storage.pdf(.+)\.pdf)$ index.php
to: RewriteRule !(\.(gif|jpe?g?|png|css|js|swf|html?)|var(.+)storage.pdf(.+)\.pdf|var(.+)\.csv)$ index.php
That should do the trick. But it is untested, please verify... Chris
