Windows 10: Very large file copy from SSD to SD never completes

I have a 300 GB file on an external Samsung T9 4TB Thunderbolt 4 SSD, encrypted with Bitlocker. This is an Acronis True Image disk backup image.I am trying to copy it over to a Sandisk Extreme Pro 512GB full size SD card, not using Bitlocker, in a USB 3.0 Sandisk SD card reader.I am using a recent LG Gram laptop 15in, with Win11 upgraded from Home to Pro. I plugged in the laptop and created a power profile in which the machine never goes to sleep, only the screen. I started the file copy. It was going around 90MB/s at first, but slowed down to the 40MB/s range after a few minutes. Windows stat

Cannot copy music files to SD card

Dear Arnie,

Thanks for your suggestions and see below...

Put card into surface and run scan; all ok

Files will not copy to music folder (either mp3 or jpeg or excel) I tried all sorts of files ad none would work

I did copy a music file to "videos" on the card and it copied perfectly (since deleted it)

It seems the "MUSIC" folder on the card is locked to copying when the card is in the phone because I CAN copy music files to it when it is in the surface pro.

Music is default to save to SD card

I cannot see to add music in groove as I already have over 7500 songs on my 200GB card.

Many thanks,

A.

 

Java.nio.file - Copying files

You can't copy a folder, thats why it generates an exception (you are trying to copy a folder using a copy file function).
You probably need to list all the files inside that folder and copy one by one

Issue was the above, so thanks temp02.
