A Text Filtering Technique Based File Retrieval Tool

To solve the problem of manually retrieving large amounts of files which is tedious and inconvenient in daily life, a file retrieval tool based on text filtering is proposed in this paper. This tool can extract the content of file which is in a specified address range and with specified file format, filter the content for keywords, and return the retrieved information. This tool can reduce manual labor, improve work efficiency, and provide high practical value for both administrative staffs and scientific researchers.
