I have two different utilities (one written in VFP and one written in VB) which create the same basic sequential text file. Records exported are taken from the same table.

When I try to import the text file from the main application, one file gets imported. Attempting the same import to the second file fails...invalid file for no apparent reason. I visually compared the files and I see no diffenrence (bytes are equal).

I do not have access to the source code of the two utilities...

Could the files be different?...and if yes, is there a tool that allows me to find the differences?

Thanks.
