A ZI_ file is a renamed .ZIP archive. To open a ZI_ file, change its extension to ZIP. Then unzip the file using any ZIP-compatible application.
To rename a ZI_ file in file explorer, select the file. Click its name again. Change the extension to ZIP. Press enter. Alternatively, right-click the file. Select “Rename” from the menu.
The underscore in the ZI_ extension prevents accidental expansion if double-clicked. It also bypasses some antivirus programs. To open, rename ZI_ to ZIP. Then use a zip program like WinZip, WinRAR or 7-Zip.
ZI_ files are created by compressing files as ZIP. Then the .zip extension is renamed .zi_. Simply rename back to .zip to open. ZI_ files distribute software and files blocked by antivirus.
The “p” in ZIP is replaced by “_” in ZI_ to avoid expansion. Rename to ZIP before decompressing with WinRAR. WinRAR compresses efficiently using multimedia, executable and library files.
