Question

I have a large file in windows XP – its 38GB. (a VM image)

I cannot seem to copy it.

Dragging on the desktop – gives error of “Insufficient system resources exist to complete the requested service”

Using Java – FileChannel.transferTo(0, fileSize, dest) fails for all files > 2GB

Using Java – FileChannel.transferTo() in chunks of 100Mb fails after ~18Gb

java.io.IOException: Insufficient system resources exist to complete the requested service
at sun.nio.ch.FileDispatcher.write0(Native Method)
at sun.nio.ch.FileDispatcher.write(FileDispatcher.java:44)

at sun.nio.ch.FileChannelImpl.transferToTrustedChannel(FileChannelImpl.java:439)
at sun.nio.ch.FileChannelImpl.transferTo(FileChannelImpl.java:510)

I mean – the computer has 3GB of RAM. A 100GB buffer should be enough!?!?

Apparently the DOS commands “copy” and “xcopy” also fail.

(edit) I’ve tried COPY & XCOPY – these fail with the same error. XCOPY seems to take a really really long time about it too.

I’ve heard of Robocopy, but it doesn’t copy single files?

I’m really feeling that Windows is for the lose right now. Surely microsoft have heard of files larger than a few GB?

Thanks!

Well – I’ve not managed to find a way that works.

None of the packaged tools in windows will copy the file. Drag and drop, COPY, XCOPY, java – all fail to copy the file.

The reason I wanted to copy the file was for a backup before doing an OS upgrade.

In the end i booted into knoppix and copied it.
