Serious Text Folder Import problem

After performing a series of successful operation with Applescript and Text Wrangler I finally end up with a folder with several files UTF8 encoded on my Mac (Snow Leo 10.6.8)

Trying to import this folder as text files (Text files only, no gremlins aka weird characters ) FMP12 keeps importing a folder whose content is not the same as the one I attempt to import.

It returns the same number of files, however as if the last Applescript TextWrangler operations did not happen, example I delete various parts in the text files, and create "pointers" so I can extract fields to create my db automatically.

I rebooted, moved the folder elsewhere, changed the encoding to UTF16, erased FMP12 prefs and db in my user library.

No result.

As the various conversions involve several files, and a lot of time I wonder how FMP12 "remembers" the "wrong folder" and how can I import the folder I need.

Thanks for any help
