A 100% save is someone else's finished career. Installing it deletes the progress in your local folder unless you copied that folder first.
Steps
- Close the game.
- Follow the save-location page and copy the folder to the desktop.
- Replace the files only after you know which region the upload claims.
- Launch, look at the garage, and restore your copy if the cars are wrong.
A smaller hammer
Extra Options can unlock cars and cash without importing a stranger's file. Built-in phrases on the cheat table add bank inside your own profile. Both leave your stage progress intact.
Questions people ask
Where does the file go?
In %LOCALAPPDATA%\NFS Underground 2\ on Windows 10 and 11. Not next to SPEED2.EXE.
Will a US 100% file work on an EU disc?
Do not assume it. US and other regions do not share the RSX and Civic versus the 106 and Corsa. A mismatched save can show cars your disc should not have.
Does this site host the file?
No. Find a file on a mod site you already trust, or skip the download and use Extra Options.
