Plain text files. Such files include text documents, source code, HTML files, XML files, comma-delimited data files (CSV), SQL queries, etc. PowerGREP supports various text encodings (Windows code pages, ISO-8859, Unicode, ECBDIC, KOI8, etc.) and line break styles (DOS/Windows, UNIX/Linux, Mac).
Binary files. These files are not human-readable without the proper software. With PowerGREP, you can search through binary files for text or hexadecimal data.
Microsoft Word documents (.doc and .dot files)
Adobe Acrobat documents (.pdf files)
Microsoft Excel spreadsheets (.xls files)
Lotus 1-2-3 spreadsheets (.wks and .wk1 files)
Quattro Pro spreadsheets (.wq1, .wq2 and .wkq files)
ZIP archives are handled transparently. PowerGREP will treat them like regular folders, unless you disable the option to search through archives.
