EF Find is a powerful search program for Windows. Look for files, text, HEX sequences and regular expressions inside 7-Zip, ACE, ARC, ARJ, BZIP2, CAB, CPIO, GZIP, IMG, ISO (ISO9660), LHA, RAR, RPM, SFX, SQX, TAR, TBZ, TGZ, TXZ, XZ, ZIP, Zip64 and ZOO archives.
It works as a stand alone application, or together with EF Commander. If launched within EF Commander, EF Find starts in the path currently selected in EF Commander. EF Find and EF Commander communicate: for example, the "Go to" function in EF Find shows you the found file or directory in EF Commander. If launched as a stand-alone program, EF Find uses Windows Explorer for this operation.
