Disk space is an important requirement for Vox Studio to run satisfactorily. Although Vox Studio will warn you when it cannot continue due to low disk space, it is good practice to always check your available hard disk space before starting a lengthy recording project or conversion session.
Naturally, for conversions, Vox Studio needs enough free disk space to store the original voice files and the conversion results plus some temporary scratchpad files. This does NOT mean twice the size of the original files! It all depends on the sampling rate and format used. Remember that 16-bit files at 44.1 KHz take up 30 times more disk space than the same prompt in 6 KHz ADPCM format! It is up to you to make sure there is enough space available on the hard disk used.
Vox Studio uses your "Temp" directory as a scratchpad area. It is therefore important that this temp directory resides on the local disc (partition) with the largest amount of free space and that there is enough free space on it to hold all the work files and temporary files. Remember, the hard disk partition that hosts your system's "Temp" folder may not be the same as your working partition. Vox Studio uses the standard Temp of Windows or the folder you have selected in Tools/Options/System. If you want to find out what the standard Windows Temp is, just open this dialog box in Tools/Options/System and press "Use Windows temporary folder".
