I have read, regarding RISC OS, that

The file system abstraction layer API uses 32-bit file offsets, making

the largest single file 4 GiB (minus 1 byte) long.

Now, that makes me wonder whether Ubuntu Linux, or, UbuntuMATE Linux,

is limited to 32 bit.

I think the file size limits depends on the files system in use as well as the OS.


The reason that this has arisen, is that I have a 4.5GB file that I

can not move - I have tried to move (using cut and paste) the file,

using both caja and PCManFM, and, with both, I get the problem that

the file is "too large to be spliced", and, a filesize limit of 4GB

apparently applies


So, is Ubuntu Linux, or, UbuntuMATE Linux, is limited to 32 bit, or,

are the file managers limited to 32 bit operations?

What is the files system to which you are copying the file? And what is the file system where the source file resides?

ext4 support up to 16TB sized files.

fat32 only supports up to 4GB.

ntfs supports up to 16EiB (Exabytes)!

You could also try using the cp command in a terminal to copy the file and see if that gives you a meaningful error message.

Hope this helps.

Regards,
Tony.
