Empty file generator tool What is a empty file generator?
This browser-based utility creates a zero-byte file with any extension. You can create empty text files (.txt, .log, .out, …), empty documents (.doc, .pdf, .xls, .ppt, .rtf, .odt, …), empty images (.png, .jpg, .bmp, .tif, .gif, …), empty audio files (.mp3, .m4a, .flac, .aiff, …), and many others. Each file that's generated is 0 bytes in size and does not contain additional data such as headers or file information. In the options, you can enter the desired file extension of arbitrary length. As soon as you enter the extension, the file is availab for download via "save as" and "download" buttons. Filabulous!
