This file is the of a "split" 7-Zip archive. When a folder (in this case, "Images") is too large to upload or transfer in one go—perhaps because of email attachment limits or file hosting restrictions—users split the data into smaller chunks. Images.7z.001: The beginning of the archive.
The file doesn't contain a full image; it contains a fragment of a compressed stream. To see what's inside, your computer needs the "map" located in part .001 . How to "unhide" your images

Every file must have the identical base name (e.g., they must all be named Images.7z.### ).
