FAT32 limitations - cross platform data exchange
Which operating system(s) are you running on all your computers ?
"Martin Trautmann" wrote in message ... Hi all, what's the limit of FAT32? AFAIK the 128 GB limit is gone on most newer Win systems. How about file size? Example: I got an external USB2/FW400 drive with 250 GB. I wanted to put backup data into a DVD disk image ( 4 GB), port it to a Win PC and burn a DVD. There's bigger files (mainly databases, probably videos to come) which I don't want to split. Is there a file size limit of former 2 GB, now 4 GB or anything else? Is there a better file system for cross platform usage? Mac takes HFS+ Mac may read NTFS, but maynot write it. Mac option is UFS - which is hardly known on Win!? I might use a HFS driver for Win instead. I don't know about UFS2/EXT2/EXT3, neither on Mac, nor on PC. However, Linux compatibility via USB/FireWire would be interesting. What's your recommendation? Thanks, Martin |

FAT32 still have 4 GB file size limit, no matter what OS.
In Win9x it's limited further to 2GB. "Martin Trautmann" wrote in message ... Hi all, what's the limit of FAT32? AFAIK the 128 GB limit is gone on most newer Win systems. How about file size?

[This followup was posted to comp.sys.ibm.pc.hardware.storage and a copy
was sent to the cited author.] In article , t- says... Hi all, what's the limit of FAT32? AFAIK the 128 GB limit is gone on most newer Win systems. How about file size? *ALL* versions of FAT (12-, 16-, and 32-bit) use a 32-bit file-size value in the directory. This limits individual files to 4G. If you want files over 4G, you must move to NTFS or other. -- If there is a no_junk in my address, please REMOVE it before replying!

Linux has no issues with ext2/3, ReiserFS, ... on USB and FireWire. Move it around all you want, it works. The limits are consistent. The only problem may be if you use older kernels or programms without large file support. In that case files 2GB will be problematic. A curent 2.4.x or 2.6.x kernel will fix the limit in the filesystem. If an application does not have large file support, it can often be added by defining one symbol and recompiling.

The easy way is to split the file on unix, copy bits to USB, then join on
windows: copy /b U:big.iso.* big.iso "Martin Trautmann" wrote in message ... |
