Active Sync won't sync all files

[cozmicray]

Hi to all hope someone has had this problem and can help me? I've been using my xda2 for approx 3 years all has gone pretty well apart from the odd re-set (hard & soft) the problem I'm having is when I connect my PDA there is always 2 files that active sync can't synchronize. I can't seem to find which files they are and why it's started to do this all of a sudden. I've done a soft re-setand this morning I deleted my partnership and created a new one but it's just the same. Any help would be much appreciated thanks in advance Ray:)
