Disputes under the FCRA dont remove "files." Files remain.
You dispute items of information in your credit file under FCRA 611(a), not credit files.
For example, you could dispute a charge off. If your dispute is successful, it would not remove the OC account from your CR, and thus the preceding multiple account delinquencies that led up to the charge off.
What did you dispute, and how was it resolved?
Each dispute is directed to one piece of information in your file.
Do you still have other negative information on your report, what is your utilization, were the accounts removed some of your oldest accounts.
Many, many things factor into a FICO score.
