Windows comes with a search function of its own but many users like to turn it off owing to many reasons such as constant indexing of the files on the hard drive which makes the hard drive running non-stop all the time. If you also have turned off the Windows Search service in your PC, then you might want to use some other third-party file search utilities like EF Find.
EF Find is a Windows file searching utility developed by EF Software and contains many advanced features that can help you find the files using a number of criteria. This utility can be used for simple file searching using filenames or file paths using wild cards. For this, you have to just specify the folder to be searched and the filenames to look for.
But a little more advanced use of the EF Find tool is for searching for files that contain a particular string or data. You can specify the string text to search within each of the files as it goes through a directory. But the text search works only for plain text files. If you want to search for any data within the binary files such as EXE or JPEG files, then you can specify a HEX string and it will find all the files that contain that data.
EF Find utility fulfills its file searching role very well. It can search for files, text or hex data in normal files or even inside the compressed archives. The program can search for data in the compressed files such as 7-Zip, ACE, ARC, ARJ, BZIP2, CAB, CPIO, GZIP, IMG, ISO (ISO9660), LHA, RAR, RPM, SFX, SQX, TAR, TBZ, TGZ, ZIP, Zip64, ZOO. EF Find also supports WCX plugins, which allows you to extend support to additional file formats. The tool is fully compatible with all versions of Windows.
