Can wordpress create link for user download sample application ?

It is nothing more than a link to a file on the site. “HTML Links”

1) upload the file you want to share with your readers to your site.

2) post a link that points to the location of the uploaded file on your site

Example: If you wanted to share a text file named “report”;

<a href="http://yoursitesname.com/wp-content/uploads/report.txt">Download My Report</a>

Make sure to include the exact name of the file and the extension, and make sure the link points to exactly where you put the file on your own site.

1) No. I can’t offer any sites for file sharing. You may want to check on Google.

2) Yes. That is a wordpress site.

I don’t have a site now , can you pls let me know it there any site allow me to upload my file , so that i can create a link for other to download from my blog .

You have a wordpress blog at wordpress.com I think. http://ww.wp.xz.cn/support/topic/364092?replies=1

Maybe support at wordpress.com could tell you if it’s okay to put the files on your blog site over there.
