I don’t know much about cables so if type something wrong forgive me …
I was wondering around with some old stuff, and found this cable that is usb to usb “as shown in the image below”

Now what i thought was that it might be used to connect 2 computers with each other so i tried that and connected 2 computers with each other using it and nothing happened Can anyone tell me what this cable is even used for ???
Thanks for the info, I have another question. Can it be used to connect one pc to another maybe for sharing files or for doing some other stuff ?
Generally no - USB connections are asymmetric, with hosts and devices. Your PCs are both hosts - they cannot function as devices or communicate with other hosts.
Not without special support from the hardware and software. But a smartphone is pretty much a PC with specialized hardware and software. And you can certainly plug your smartphone into a PC to share photo’s.
If it was already tried with this specific cable and it didn’t work, then this cable doesn’t have the capability built in. Some cables like this have a bridge in the cable that allows pc to pc communication.
Laplink is a major product that still does this. In the center is a controller that acts as a device to both ends, letting both PCs act as a host.
It still requires their software to make use of this connection, though.
