Hi, I'm Robert and I'll be helping you with your financial software question.
I can not put on the flash drive what was not there before. But if you cant get your data into quicken you don't know what is on there or not for sure because you may be looking at the create date for the file rather than the modify date.
If you still have the old computer running the quicken what you want to do is open the quicken on the old computer
file / save a copy as
and save a new copy on the flash drive with a new name. That way you know that it is there.
copy the flash drive to a folder on the new computer.
in the quicken on the new computer go to
file / open
browse to the folder that you copied the flash drive to and select the file that you created above.
Alternatively you can just copy what is on the flash drive to a folder on the new computer
open the quicken and go to
file / file operations / find quicken files
and it should find any files that are on the computer.
