How do I Compress a 1.8GB file

[ThestigGT999]

to 980MB

I have tried winrar and power iso

The file is OVA (Open Virtualization Archive) for virtual box

thanks in advance

OVA files contain data which is already compressed, you may have some luck compressing the file a little bit more but I wouldn't have thought you could get anywhere near 980mb.

oh ok
