Never download another 100mb test file or waste time searching for a large file. Sometimes you need a large file fast to test data transfers or disk performance. Windows includes a utility that allows you to quickly generate a file of any size instantly.

Open an administrative level command prompt.

Run the following command:

fsutil file createnew <file> <size in bytes>

For example, this command will create a 1GB file called 1gb.test on my desktop:

PS D:\> fsutil file createnew testfile 3221225472

The key is to input the size of the file in bytes so here are some common file sizes to save you from math:

1 MB = 1048576 bytes

100 MB = 104857600 bytes

1 GB = 1073741824 bytes

10 GB = 10737418240 bytes

100 GB =107374182400 bytes

1 TB = 1099511627776 bytes

10 TB =10995116277760 bytes
