Make File Size Bigger

You can create a file of any size using nothing more than what's supplied with Windows. Start by converting the desired file size into hexadecimal notation. You can use the Windows Calculator in Scientific mode do to this. Suppose you want a file of 1 million bytes. Enter 1000000 in the calculator and click on the Hex option to convert it (1 million in hex is F4240.) Pad the result with zeroes at the left until the file size reaches eight digits—000F4240.

Now open the command prompt window by entering cmd in the Start menu's Run dialog; in 

• Enter the command DEBUG BIGFILE.DAT and 
• ignore the File not found message. 
• Type RCX and press Enter. 
• Debug will display a colon prompt. 
• Enter the last four digits of the hexadecimal number you calculated (4240, in our example) and press enter. 
• Type RBX and press Enter, 
• then enter the first four digits of the hexadecimal size (000F, in our example) and press enter. 
• Enter W for Write and Q for Quit in capitals. 

You've just created a 1-million-byte file using Debug. Of course you can create a file of any desired size using the same technique.

How to Remove Write Protection Error In Usb Drive

In the Write Protected error, we can’t write or copy any data in our flash drives and even can’t format the drive.There are many reasons that cause this problem, let’s see solutions of them.

Solutions:
• First of all try to locate a small switch (if any, that you may have not noticed) at some place on the drive or memory card reader. This is the prime reason for this error. If there is one, switch it to the other side to turn the protection off.
• Yes I know this problem is also occurring these days without this switch but not to worry. Just download this helpful software from here and run it to execute a “low-level format” on the drive. This software is quite handy and may take few attempts to actually remove the error.
• The problem can also be caused by some virus activity so just get it scanned by some updated good anti virus which may solve your problem.
• BUT if none of the methods listed above solves your problem then your pen drive might have gone corrupted, so just get it replaced.

1: After the low level format, you may need to “Partition the drive“. Dont worry, partitioning a pen drive means allocating it its File System and Cluster Size that was lost after the Low Level Format.
For that:
Run diskmgmt.msc in Run.
In the disk management window, select the pen drive, right click on it and click on Format.
Now choose the File System and Allocation Unit Size and do not check the boxes below.
