 22 Feb 2003 17:19 Single File size exceed 2GB? |
|
|

Dear all,
When I use tools to generate report file exceed 2GB, it makes core dump!
Does Linux support a single file exceeds 2GB?
What is the partition format I must choose?
Thanks
Ejean

Linux supports files greater than 2GB if kernel is 2.4.x or greater
also the programms must support it too

| At the Windows platform you have to use NTFS to support filesizes above 2GB. FAT32 doesn't support files bigger than 2GB. I don't know about Linux.

| On Linux you can use files bigger than 2GB with no problems. Use EXT3 file system , this is the default file system for most Linux distributions.

| The limitatation of a 32 bit EDA tool is 2GB ( 2^32 =4GB, some system use 1 bit for parity bit, so the limitation is 2GB). So there are no way you can avoid that. The only way is upgrade you OS to 64 bit and use 64bit Application and the limit will be the sky ( 2^64 = ?). But there are few PC machines and applications now have 64 bit capability. That's why we have to stuck with expensive and slow Sun machine for a while

are you sure that this bit is for parity?
I'm not... but it doesn't matter - you are right that
2^32 = 4GB, and largest file is aprox 2GB...
look for large fs...
