url returns the url at which the file is available when accessed via
the web server - as you have demonstrated below, the file isn’t at /
system/previews/…
The path method returns the local path to the file.

Even when I changed the path to like

file = 'C:\Documents and
settings\Administration\project\public\system\previews\3\original\FTpreview.zip

I get error as : …\FTpreview.zip not found.

Can you help me.

let me post new code.

You’d need to escape the backslashes. Not sure how ruby handles
windows style paths.

Here is the code and error list below. After creating a zip file in
original folder. When I tried to run the from rails console, it works
great, but getting error when user tries to upload. So, I thought of
doing a delay job, and tried to run same code in show action but got
same error.

Any help would be great.
