Hi Abhilash,
We export in an application and not from the CR designer.
If I export or save the report with the "Save data with report" from the CR-designer everything is working fine.
We created a work around by exporting the report to a PDf file on disc. that doesn't create these weird files.
Actually the date and time and the size of the file exactly meet the file size of the file as created in the designer when exporting it to Crystal Reports format on disc.
