Hi,
Is it possible to edit an existing .epw file in .epw creator ? I tried, but couldn't open it in .epw creator.
Any suggestion will be highly appreciated.

Best regards.

No, the .epw creator you downloaded from www.iesve.com/support/weathefiles has been modified so only the fields required by the VE are used in the .epw files. If you want to use an existing .epw then i'd recommend opening it in Vista and then exporting the data you need to a spreadsheet by copying/pasting the data into the relevant columns, you can then edit the data as you wish.
