Dolphin fails after copying the first 4 GB of a large file when the target file is located on a FAT-formatted USB memory stick. Reproducible: Always Steps to Reproduce: 1. Tell Dolphin to copy the file openSUSE-Tumbleweed-DVD-x86_64-Snapshot20150909-Media.iso to a FAT-formatted USB memory stick. Actual Results: 1. Dolphin copies the first 4 GB of the file, fails and leaves the target file incomplete. Expected Results: 1. Let Dolphin recognise that it cannot allocate such a large file on a target device and offer to split the file into parts.

Thanks for the report. (In reply to Christopher Yeleighton from comment #0) > Expected Results: > 1.

Alternatively, simply display an error message and tell the user that it's not possible to copy the file. In any case, this looks like a KIO issue.
confirmed. plasma: 5.12.3 framework: 5.44.0 application: 17.12.3 But even "cp" starts to copy the file and stops at 4 GiB (message "File too large") as well as rsync.
