Search Through Files Compressed with WinZIP, 7-zip, WinRAR, GZip, BZip2, etc.

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. This is particularly useful when extracting information from archived documents, or when gathering statistics from compressed log files.

With PowerGREP you can work with zip files and other archives as if they were regular file folders. Files inside archives are decompressed on-the-fly. Now you can save hard disk space or place more files on a CD or DVD by compressing them, and still search through them as usual.

When collecting data or converting many files, PowerGREP can save the results into one or more new zip archives, even if the original files were not compressed. This is particularly useful if you plan to email the results. Now you need to attach only one zip file.

If you like to keep backup files around, save disk space by telling PowerGREP to compress backups into zip archives. Use the "numbered archive" backup type to create a new archive for each action's backup files. While PowerGREP's Undo History handles zipped or regular backup files just the same, a single zip file is handier if you want to archive backups outside of PowerGREP.

Skipping ZIP Files and Other Archives

Of course, 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.

Archive Formats PowerGREP Can Read and Write

All of PowerGREP's features are available for these file formats. PowerGREP can modify files inside these archives and add files to them and delete files from them. It can also create new archives using these formats.

Formats That PowerGREP Can Decompress Only

PowerGREP can search through files stored in these archive formats, but it cannot save modified files back into the archive. PowerGREP does provide extensive options for saving the modified files elsewhere, compressed using one of the above formats, or not.

"I can’t tell you how often this program comes in as a lifesaver when researching data issues for me… just today I needed to sift thru 150 zipped files with roughly 10,000 files inside, and PowerGrep not only handled it, but faster than any of us imagined possible."

"I just want to tell you that you have a great program there. It turned a job that could have taken hours into a few minutes. The Microsoft OneCare back up system creates ZIP files, hundreds of them. We use an external hard drive and OneCare backs up the files over our network. My daughter is a college student and her computer died. She needed all her notes for one of the topics for a final exam and by using PowerGREP we were able to search the backup drive and get her files immediately to load on another computer for her to continue her intensive studies.
