The 003 indicates this is a "split" archive. For the data to be usable, you must have all preceding parts (e.g., 001 , 002 ) in the same folder. You cannot extract 003 in isolation; you must start the extraction from the 001 file. 🔍 Identifying the Contents
"Comp" may refer to "Competition" data (e.g., from Kaggle). Look for .csv or .json files inside.
