Hi,

I’m trying to download a file with net::IMAP from mail count. I can  
download plain texts files using fetch method and unpack’m’, but when i  
try it with an excel file (vnd.ms-excel), the downloaded excel is  
corrupted.

thanks for all

Hi Artur,

I have compared the excel file download from mail with the original and  
seems to be the same. I’ve read that can be that the LF character has  
been replaced with CRLF characters, so the download file size is  
diferent.

thanks

Hi,

At last I found the solution, to download correctly excel files I use  
the ‘wb’ instead of ‘w’ on the open parameters.

if body.subtype == “PLAIN”  
File.open(nameFile,‘w’)  
f.write(file)  
end  
else  
File.open(nameFile,‘wb’)  
f.write(file)  
end  
end

bye
