First i would like to say thank you for all the help so far. I would like to start again to clarify the problem to make sure we are on the same page. I found a .dat file that i would like to convert to a .psarc. I read on this forum that using the toolkit i can extract files and use them to make a .psarc. Having done so i was to find in the directories the .xml file. I have found this file and tried to use it in the tool kit under the creator, arrangements tab. Where it asks me to add the .xml file i have added the .xml metioned above. The toolkit then reads "you appear to be using an old version of Eof please update first." "choose an appropriate arrangement" I do not know how to use the Eof to update this file. Eof does not recognize the files when i select load. Does the toolkit do this for me automatically or do i have to update manually. Again thank you for all your help.
