Laptop spoilt, how to transfer to my new laptop?

My laptop spoilt and they said unable to repair due to motherboard not working.
So I bought a new laptop and Sata to USB enclosure

I able to open my old SSD harddisk but I can't find all my saved file.
How to get back all my files?

 

Let's work on terminology first. There are two main types of disk drives in use these days; the traditional hard disk (or hard drive or HD) and the solid state drive (or SSD). The hard disk uses a motor to spin platters (disk) that store the data by using magnetic particles on the platters arranged one way or another to represent the 1s and 0s. It then uses another motor to "step" a Read/Write head across the platters to the various data storage locations.

SSDs have no moving parts at all. They use transistor "gates" that are electronically switched open for "0s" or closed for "1s". They access those storage locations directly and electronically through the circuitry. That is, there is no mechanical R/W head assembly that moves back and forth.

Hard drives are "electro-mechanical" devices. SSDs are purely electronic.

There is a "hybrid" hard drive that is really a hard disk with a small solid state "buffer" built in to the logic board instead of regular RAM as used with regular hard drives. But these are not widely used.

My point is, there is no such thing as a "SSD harddisk".

Now to your question. You may not be able to get your files back. It depends on what type drive you really have, and how the files were deleted (or corrupted). You can try using Recuva from the makers of CCleaner. SSD Drive Recovery Software is another you can try. But don't get your hopes up too much.

You likely don't want to hear this, but it is cases such as this for why keeping current backups of data we don't want to lose are so essential.
