I do own TS2010, yet never installed (or registered) it, so you got to check if this is possible:
- Can you see what is locally modified?
If so:
- Make it a habit of deleting and re-downloading all the content that you upload. That way you can easily see what you did not upload yet: Those locally modified.
I also make it a habit of archiving my local assets every now and than so that if I accidently delete something that I have no uploaded yet I can regain it from an archive.
Another solution would be to have a 2nd clean install and simply filter in CM on your own name (or use the website version of the DLS for that to avoid a 2nd install).
