I have a handy button that I use constantly to make a copy of a file and add a date/time stamp to it:
@nofilenamequoting
Copy DUPLICATE WHENEXISTS=rename AS "{file|noext}_{date|yyyyMMdd}_{time|HHmmss}{file|ext}"
It's always bugged me that it uses the current date/time - I would prefer it used the file's modified date/time. There doesn't seem be control code in version 9.x of DOpus for getting a file's modified date/time - can anyone tell me if it is possible in version 10?
