non-html files, such as txt, pdf are viewed outside the portal, so you need to specify the relative path with /content (if your file is under the default portal, try localhost:8080/portal/content/pathtofile)
The file itself is stored in your CMS folder, which is in JBOSS_HOME/default\data\portal\cms.
Hi Rali thanks for your answer
but it seems that I'm not able to reach the file
Even if I go to JBOSS_HOME/default\data\portal\cms folder i'm not seeing the files although in the portal I see the title of the file in the CMS Admin...
Maybe It just the title and it's not actually upload it, or maybe it on the Oracle DB?
Do you have any clue
Don't know what to do..
