Making HUGE files in Windows

[SUOrangeman]

Someone needs to make a 50GB file to test a RAID array *in Windows*. Is there something simple that can concatenate files to create bigger ones? The initial small files will just be ASCII.

Also, is there a way to time individual DOS commands. Time the concatenation and then the juggling of 50GB will be measured.

Thanks in advance.

Never mind. 🙂

copy a+a b for ascii
copy /b a.exe+a.exe b.exe for binary

Apparently 'time copy a+a b' might work for timing purposes.

Hmm, does Windows really let's you to make bigger files than 2,1Gb without some sort of special utility ?

FAT32's 32-bit addressing system will only allow for individual file sizes of up to 4GB. I think it's safe to assume you are using NTFS on that RAID array? Just thought I'd let you know since a guy at work couldn't figure out why he couldn't edit a digital home movie on his Win98 machine. It was about 6GB in size uncompressed and whenever it hit 4GB in size on his drive, it would stop with no discernable error message. I actuall found a Knowledge Base article from Microsoft that stated this information. NTFS has a theoretically limit of something in the realm of 6EB (exabtyes).

Why, thank ye, DAM.

Actually, I'm just posting the results of the 50 e-mail that flew across my work inbox in about 3 minutes. 🙂

I am not so sure that the 'time' things works though. I may be getting *NIX and Windows mixed up. I never tried any of this myself.

The DOS time command displays the current time and prompts you to change it. It doesn't actually time anything. 😉
