Summary
The “data error exclusive” message appears when MO2’s built-in FOMOD (installation script) or archive extractor cannot unpack a mod archive (usually .7z, .rar, or .zip). Unlike a simple CRC mismatch or “file in use” error, “exclusive” suggests a file access conflict – the extractor cannot gain exclusive read/write rights to a temporary or destination file. This is part of MO2’s “data error” family, but with a specific lock-state nuance.
