Abstract: A new approach is proposed that contemplates systems and methods to support scanning through a file of large size without having to load the entire file into memory of single file parser or scanner. The proposed approach is configured to divide a ginormous file to be parsed and scanned into a plurality of sections following a divide and conquer scheme. The plurality sections of the file are then parsed and loaded to a plurality of file scanners each configured to scan its allocated file section of a certain file type. Each of the plurality of file scanners is then configured to extract and evaluate from its allocated section file parts that can be harmful to a user of the file and/or expose sensitive/protected information of the user. The scan results are then collected, analyzed, and report to a user with a final determination on the malicious content and sensitive data.
