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.

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.

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.

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