Copying files while my Mac is in sleep mode

Hello everyone,

I am copy some videos from my laptop to an USB external drive. There are 80GB of videos so it will take some time. After a few minutes the laptop entered the sleep mode. In the end the 80Gb were not transferred to the External Hard Drive. Could it be because the laptop entered the sleep mode ?

That would be the case for a Windows machine. Set power management to disable sleep when on AC power. That is what I do.

You should turn OFF:

and
all other power saving measures

so john you confirm that as soon as the laptop entered the sleep mode it stopped copying the video to the external hard drive.

One more questions: in the C;Drive of the laptop there are 2 or 3 copies of the same videos. if I copy the same video 2 times to any external hard drive does it take double space ? for example if I have a video that is 1gb and I copy the same video two times to an external USB hard drive it will take 2gb of space or 1 gb of space ?

Internet and network activity stops when the computer suspends, so yes copy stops upon suspending.

If you copy the same video to an external hard drive, you will be asked if you wish to overwrite or copy to a new file.

The first method (overwrite) does not use more space. The second method (make a copy) does use more space.

ok thank you for confirming my doubts.

new question: John check the pic that I have attached. I opened photos and under photos there is VIDEOS. copying all the videos from VIDEOS to an external USB hard drive, then deleting all the videos that are in VIDEOS will free up 80GB of space in the laptop ?

Where is the default location of that VIDEOS folder please ? do you know ?

If you copy the videos to a drive and delete the videos from the laptop, then you will recover space on the laptop. Copy followed by Delete equals Move. Moving files takes space on the target and frees up space on the source.

The videos are likely in your personal laptop folder.

this is a client laptop. she has been storing data for 6 years for a total of 500gb. its a real mess. there are things everywhere. I need to free up at least 150gb. I will know tomorrow if deleting the videos from that location I showed to you in the pictures will frees up space in the C:drive of the laptop.
