my downloads folder was erased after doing an update to laptop

[Khatzam]

my computer completed an update but there wasn't enough space so it deleted some files. I did not know it was going to erase my download file. How do recover my dowmload file?

My guess is -- you probably can't!  Why? Because when space is freed up, new files that get created start writing to that space, effectively overwriting what was there before.

All you will be able to recover at best from the drive is personal data -- and even that requires that the deleted files have not been overwritten:
1) Insert a USB stick into the PC that is large enough to hold all the files and folders you want to recover. You need this because you can not recover erased or deleted files to the same drive.
2) Download and install this utility

2) Run the data recovery utility to see what can be retrieved from the old drive.

If that tool does not find what you need, an alternative is Recuva http://www.piriform.com/recuva

And, if that does not work well, the best tool out there is this one, but only the demo version is free https://www.runtime.org/data-recovery-software.htm
