: Identifies this as the first segment of a sequence (followed by .002, .003, etc.). 2. Association with Virtual Forensic Computing (VFC)
: These archives often include checksums to ensure that not a single bit of evidence has changed during the compression or transfer process. 3. How to Extract the Data
: Once extracted, you will typically find a .vmdk (virtual disk) or a folder containing forensic report data. Summary Table File Type Split 7-Zip Compressed Archive Common Use Digital Forensics / Software Distribution Primary Tool 7-Zip (Open Source) Requirement Must have all numbered parts to open
You cannot open .001 files in isolation; they are like the first chapter of a book. To access the contents:
The file is a specific type of compressed archive, representing the first part of a multi-volume 7-Zip split archive typically associated with Virtual Forensic Computing (VFC) software or large forensic data exports.
: Right-click the .001 file and select "Extract." The software will automatically "stitch" the parts back together to recreate the original large file.
When data—such as a forensic image of a hard drive or a complex software installation—is too large for a single file or needs to be shared across platforms with file-size limits, it is "split."
: Forensic exports are often massive. A VFC.7z.001 file is likely part of a compressed "triage" report or a portable version of a virtualized machine meant for evidence review.
