Please tell us your exact version of Lightroom, your OS as well as the amount of RAM and free space on your drives.
This usually has noting to do with the RAM, though. It usually tells you that there is not enough space on the (target) drive.
Is Adobe Photoshop Lightroom CC, Ram 6.00 GB (3.25 GB usable), Thank you
Mac or Windows? What version?
Do you have a 32-bit OS? That limits memory significantly. Or if you have 6GB total why does LR only have use of 3.25GB? I find 8GB on a 64-bit OS still a bit too small.
Please completely respond to the questions already asked:
- Exact version of Lightroom (CC 201x.y)
- OS version
- How a bout free disk space? Does your export target have enough free disk space as well?
The message "not enough memory" means exactly what it says. Your copmuter does not have enough memory to complete the task.
To fix the problem, you could upgrade your computer to have BOTH a 64bit operating system and 8GB of memory. Upgrading to one without the other will not fix the problem.
In the meantime, you might want to try exporting the photos one at a time, and making sure that no other applications are open on your computer.
