linux can access both windows and linux partitions. for FC5 you will have to use EXT3FS or EXT2FS but i would reccomend EXT3FS. if you can find the program "ext2ifs" i think it is called you can use that to access linux partitions in windows. if you can't find it catch me on msn or email me or something. i think i have the final version of it somewhere
Can Windows and Linux (whichever distro) both use & save files on the same partition of a drive, or are the file structure's different, so each would need its own file space?
Linux can't save files on NTFS partitions. You can create a small FAT32 partition for storing files with linux and still be able to access them with Windows. You cannot store files bigger than 4GB on a FAT32 partition, however.
