How to search for text within compressed file?

With PowerGREP, you can quickly search for a piece of information through files and folders on your computer and network, including files compressed inside .zip files archived using these formats.

• ZIP archives: ZIP format used by PKZip, WinZIP, and a host of other compression utilities. This is the most popular archive format.
• ZIPX archives: ZIPX format used WinZIP. Incompatible with most ZIP tools, but allows better compression.
• 7-zip archives: 7z format used by 7-zip. This format yields the smallest files of all the archive formats that PowerGREP can create.
• TAR uncompressed: Uncompressed tarball (.tar file). The most popular archive format on Linux, usually compressed using one of the four methods below.
• TAR GZip: Tarball compressed into a GZip file (.tar.gz or .tgz file).
• TAR BZip2: Tarball compressed into a BZip2 file (.tar.bz2 or .tbz file).
• TAR LZMA: Tarball compressed into an LZMA file (.tar.lzma or .tlzma file).
• TAR XZ: Tarball compressed into an XZ file (.tar.xz or .txz file).
• CPIO uncompressed: Uncompressed CPIO archive (.cpio file).
• CPIO GZip: CPIO archive compressed into a GZip file (.cpio.gz or .cpgz file).
• CPIO BZip2: CPIO archive compressed into a BZip2 file (.cpio.bz2 or .cpbz file).
• CPIO LZMA: CPIO archive compressed into an LZMA file (.cpio.lzma or .cplzma file).
• CPIO XZ: CPIO archive compressed into an XZ file (.cpio.xz or .cpxz file).
• GZip: Single file compressed with GZip (.gz file).
• BZip2: Single file compressed with BZip2 (.bz2 file).
• LZMA: Single file compressed with LZMA (.lzma file).
• XZ: Single file compressed with XZ (.xz file).

Sometimes you don't want to search through .zip files. You can tell PowerGREP to treat .zip files as ordinary files or to skip them entirely. Or maybe you want to search through archives in a particular format, but not through any other archives. The "archive formats to search inside" setting on the File Selector lets you tell PowerGREP exactly which files should be recognized as which archive formats, and whether to search through them or skip them.
