You have to precise the extension of the file you want create.
By example, you save your picture like that : picture.jpg, or picture.png. If you don’t precise, you obtain a file without extension, so this file can’t be known by Windows.
For me, this software run well, but many other software make same job. The only interest is it remains simple, and, avoids the use of software more “heavy” to opened for a simple job.
