Hi i have a folder with photos and videos that is 10gb in size is there a way i can compress this to fit on my San Disk 4gb usb drive. any help would be great thanks.
No.
Photos are already in a compressed format. If you ZIP a .jpg file it’s no smaller and in some cases slightly bigger. I suspect videos are similar. So no, there is no way to make 10gb into 4gb. Nor 8gb. You need a 16gb usb drive.
10GB to 4GB? This is not possible. 16GB flash drives are already cheap nowadays. I would seriously consider to buy it. I would even consider the 32GB version.
