Thank you very much that was a helpful answer.
I found out the data is paired-end seq and demultiplexed as well.
according to Importing data tutorial I think I should go through “Fastq manifest” formats so I created a manifest file like pe-64-manifest file but my data is 33v2.
I tried to do that with just 2 samples (means 4 files: 2 forward reads and 2 reverse reads) so it worked. but when I want to import the all data there is an error as you can see in the picture. its weird because the error is about line 3 which correctly worked when I tried to import just 2 samples. but now I cannot import the data in this situation. you can see the sample files, manifest file, and the error.
I will be appreciated if you can revise the procedure if I'm going in the wrong way.
Thank you
@mohsen_ej, could you share the manifest file you built that’s not working? I’m interested in looking at how it’s formatted, and specifically at the whitespace.
Thanks,

Sure thank you. I'm not sure if I should use "fastq manifest format" or " Casava 1.8 paired-end demultiplexed fastq" .
but in both of them there was errors.
thank you
it has solved. 
thank you for your time

Glad to hear you figured it out, @mohsen_ej! Looks like maybe you had spaces instead of tabs separating the columns in your tab-separated-values (.tsv) document?

yes, that was the reason.
