Re: [openupload-devel] downloaded files are corrupted

[Leonel I. <Leo...@co...>]

Hi Alessandro:

Thanks again for your help. I used the diff utility as you suggested and indeed found a difference. 

It the files that I download from the server have some HTML tags added, it mentions main.css. 

I did make some changes to OpenUpload. I am using Microsoft Expression Web 4 to edit my openupload site. Once I was editing the main.css file, and then I noticed there was an option that said "apply css file to all the site" (or something like that) and I clicked on it. I noticed that after this, when viewing the source code for my openupload pages, there were some extra lines at the begining with "include main.css" instruction, but I never thought it was going to affect the files I was uploading to the data directory.

Now, according to what I've seen,  this line isn't added to the files when they are uploaded, it does it to the files when they are downloaded, because the files in my openupload's server "data" directory are fine. 

I am attaching the files for you to see what I'm talking about.

So I have to find out how to "undo" this process in Expression Web 4. 

Thanks a lot for your help.

Leonel

I have absolutely no idea on why it should change the content of the files. Have you tried using different browsers?
What about antivirus software? insthead of vi, please use the diff utility to check if the file is the same.

have you modified any part of OpenUpload? It seems it's sending some extra character but would not know where.

could you try uploading a small txt file and then downloading it and attach both of them in an e-mail so I can analize them?

Alessandro
