little mistake "but i cant start VSE anymore."
There is no supported method for relocating the DAT files.
Even if you should succeed, the first time you engaged Support and we noticed it your support would immediately end until that matter was corrected.
thx for the info.
Why this feature is not a part of VSE/ePO?
Would be nice if you open a request for this feature ...
It has been raised before. As to why it has not been implemented, I do not know.
If you have a Support Account Manager this would be a good item to add to any discussions with them; and perhaps they'll be able to coordinate some time with you to share your thoughts and business need for this idea with the VSE Product Manager.
