Cam.7z.001

A .7z.001 file represents the initial segment of a multi-part split archive, requiring all subsequent numbered parts (e.g., .002 , .003 ) to be present in the same directory for successful extraction. To rebuild the original data, users must right-click the .001 file and use 7-Zip or compatible software to initiate extraction, as the file is useless in isolation.
