Not to be mean, however this is a really poor question and the answers, if you get them at all, will most likely be very unhelpful. However to at least point you in a direction. In general they all have ftp sites for bulk downloads or a link to download (in whatever format you need) next to the file you are looking at.
For more information here is the link for uniprot's help page http://www.uniprot.org/help/ and here is a video on youtube
ncbi is just as easy, if you are looking for a programmatic way of download here you go
The answer to that vague question is... at the respective websites. If you want a more concrete answer you have to ask a more concrete question, sorry.
And what should ncbi plast be (I guess you mean 'blast' but see, you gotta be more precise - if you don't know how to spell blast, I wonder what you want to do with all the data for... all species?)? Bioinformatics is complex and a huge field. And why does this have the tag 'software error'?
