I have a script which masked certain fields in a data file (fields seperated by '|'). I have done a lot of these and they work fine. However, when I copy this exact file to another folder to use a different data file (.svd) I get the "Index was outside the bounds of the array", I've seen a few other threads on this but none really answer my query.

Curious as to why it still works in a particular folder location but not the other (I am changing the input and output urls to direct to the new folder).

Error below:

Index was outside the bounds of the array.

"There is at least one record starting with STARTDELIV that does not have enough fields. find /I "STARTDELIV" "MYURL\\ABS.SVD" "
