The computer extracts a value of a feature of the candidate configuration file and aggregates the candidate configuration file with a second candidate configuration file related to the same configuration item identified from among a plurality of files from a second machine, based on the extracted value. The computer then determines a configuration file related to the configuration item from among the aggregated candidate configuration files based on a result of the aggregation, and determines a characteristic of the configuration file related to the configuration item. ## Claims ### Claim 1 A method for performing configuration management of a computer, the method comprising: identifying, by the computer, candidate configuration files from among a plurality of files from a training machine by searching the content of the plurality of files from the training machine for keywords associated with configuration items of the machine, wherein a configuration item is a configuration parameter or information that needs to be indicated when installing a system on a machine;
