Thanx guys.
Sorry Shawn have to skip this one. Never did anything with Wise installer. Need anything else

FatFile().udf great name for a UDF.
Like Joeel siad creating LARGE files takes some time. 500KB file took like 20 seconds :shoked:
Fsutil did a 50GB file in less then 1 second

For now I'll go with fsutil. Have to create files up to 100GB so FatFile() could take some time before it did that And fsutil warns if there is not enough space on the target drive. Don't want any dependencies so KF is not the choice for now either.
