Hi,
I am trying to upload a zip file from salesforce to Amazon s3. The file is taken as input from user(as blob) and then encoded into base 64. This base encoding makes the string size grater than 3MB. As the maximum size of String allowed is 3MB, i am unable to upload zip files greater than 3 MB.
Also, even if i do upload the file without using salesforce, i need to read the zip file after uploading it. This is not posssible in Amazon without downloading the zip file again.
 
Is there any work around for this? Any help would be appreciated.
Thanks in advance.
