File Size Limitation

For some reason it seems very difficult for many programmers to simply let the recorder close the first file, open a new file (using the same base filename with a number added to the end), and keep recording. This would allow the recording to go for longer than either the file system or file format allows, meaning the total length of the recording would only be limited by the amount of available space on the disk. Most DAW apps I'm familiar with do exactly this, usually in 2gb chunks by default. |

File Size Limitation
Hi,
In message , Jonas Eckerman writes For some reason it seems very difficult for many programmers to simply let the recorder close the first file, open a new file (using the same base filename with a number added to the end), and keep recording. This would allow the recording to go for longer than either the file system or file format allows, meaning the total length of the recording would only be limited by the amount of available space on the disk. Maybe that's the problem. The programmers don't like long recordings. :-/ This problem was solved a few years ago by vendors of video capture cards, in exactly the way you describe. They just create a sequence of files with a 0, 1, 2... suffix on the filenames, then recreate the whole file within the application. Early generations of such software suffered occasional glitches, such as the odd lost frame, but that seems to have been sorted out by the use of sensible caching methodologies. Matrox, Pinnacle and a few others have all implemented this type of approach, so maybe it's a case of educating the programmers. If they can do it with 30(ish) Megabytes per second of 4:2:2 video, there doesn't seem to be any reason why they couldn't do it with audio at similar data rates. -- Glenn Booth |

File Size Limitation
This link should explain a bit about FAT16/FAT32:
http://support.microsoft.com/support.../q154/9/97.asp In the MS-IE6 browser, it appears in the address field as this: http://support.microsoft.com/default...NoWebContent=1 Check it out, alternately tap "FAT32 size" (without the inverted commas!) into google and have a look at the links. ---------- My info is this: DOS, Win3.X, Win95A uses FAT16. Volume size from floppy to 4GB - maximum file size 2GB. Win95B (OSR2, OSR2.1), Win95C (OSR 2.5), Win98 and Win98SE, ME and XP uses FAT32. Volumes from 512MB to 2TB (Terrabytes) - maximum file size 4GB. WinNT4.0, Win2000 and I think XP also (I'm not exactly sure about XP here) uses NTFS (NewTechnologyFileSystem). No practical limit to volume/file size. Minimum volume size is 10MB. Depending on your Operating System, your motherboard, your BIOS, and the size of your harddrive, you may or may not be able to access over 8.4GB using FAT32. Even though you can *allegedly* get up to 2TB, or files of 4GB, this doesn't always work in practise. This is mainly due to harware limitations. More info available from support/knowledge bases at WDC.com (Western Digital), Maxtor.com (harddrives) and Phoenix.com (for the BIOS, navigate to products/bios, Award, or AMI). It goes without saying that FAT and systems are tricky bidnis. Later, -=Dubz=- |
