How to upload files in the directory listing page?

Not really sure to understand your problem, could you give an example ?

It seems that the folder title is searchable by drupal built in search.

Is it possible to include inside folders file name (as an example: example.doc when I write this name the search engine will show the page name) would be also searchable?

Thanks.

Another issue is when I upload file its creating "descript.ion" and showing new sign (red color) after uploading but this file is not there (the direcotry) before.

Can I restrict to creating this file inside the directory?

Hum... I think the best option is to filter metadata files, don't you think ? You can do it by adding *.ion in blacklisted files but we also introduce this as a default feature.

For the search feature, I'll have a look to see how to instruct Drupal not to search in filelistings.

Thanks for your response.
