deCHK v2.1 is a specialized, lightweight utility designed to recover data from .CHK files. These files are often created by the Windows system tool SCANDISK or CHKDSK when they find corrupted data on a hard drive or USB stick and move the fragments into a folder named "FOUND.000". What is deCHK v2.1?
Developed by Sascha Presnac and hosted on Techcrawler.de, deCHK focuses on identifying the original file format of these mysterious fragments and restoring them.
File Support: The tool can identify and recover over 50 different file types, including common formats like JPG, MP3, PDF, ZIP, and modern MS Office files (DOCX, XLSX, PPTX).
Version History: Version 2.1 was released on April 15, 2012, as a ZIP file (approximately 779 KB).
Portability: It is a portable application, meaning it can run directly from a USB device without needing a full installation. How to Download and Use It
You can find the official download for deCHK v2.1 on the deCHK Techcrawler page.
Extract the Files: Download the ZIP archive and extract the contents to a folder on your computer or a portable drive.
Select Folders: Open the program and choose the source folder where your .CHK files are located (usually a "FOUND" folder) and a destination folder for the recovered files. Safety risk – Obsolete software from unofficial sources
Run Recovery: Choose the "Copy" option to keep your original fragments safe, then click "Go" to let the software attempt to identify and rename the files. Why Use deCHK?
While Windows creates .CHK files to prevent data loss, it doesn't give them proper names or extensions, making them unreadable. Tools like deCHK look at the internal "header" of the file to figure out if it was originally a photo, a document, or a video, allowing you to open it again with the correct application. deCHK - recover CHK-files - Techcrawler.de
