I used A1 website downloader
however the word documents and excel files are opening in IE with some different encoding
pls help

Please write/pm/email the website address. Word files should be downloaded "as-is", so I don't believe A1WD touches them in any way. But I will be happy to check and verify this

This is a portal hosted on intranet.

all docs have garbled text , followed by some readable content followed by this

You have to open the .doc documents in a doc compatible program... For instance Microsoft Office... Open then in another viewer that can't properly view the .doc documents will make the .doc documents appear like garbled!

Try open the documents from Microsoft Word and Microsoft Excel and see if that solves the problem!
(It may be the various Office IE addins/plugins are not enabled when viewing local content. Under all circumstances, try view the files in newest versions of Excel and Word)

From the snippet you have shown it does not look like A1WD touched the documents in any way.
