A 16GB flash drive can hold 4x as many files as a 4GB flash drive. I would recommend a 16GB.

No, a 4MB flash drive will only hold about two average sized pictures. Documents vary in size a by huge amounts so it is hard to tell but it would probably not hold more than 20 documents. A 4GB flash drive(there is an enormous difference between megabyte and gigabyte) will hold about 2000 average sized pictures though.
There is only one use for a 4gb flash drive. They are used to save images, documents, video clips or sound clips and to transfer them to another computer.
Try reformatting it.
When it comes to flash drives and SSD's, bigger has more space and its faster. Going from 4GB to 8GB will not be a noticeable effect. Only 2GB to 120GB will be noticable.
The Dane-Elec Flash Drive is compatible with Windows and Mac.
No, need a new mainboard
