ubuntu - File too Large python

Question

I am writing to a file using python. The script suddenly stops running and throws an 'IOError: [Errno 27] File too large' Is there a limit on the size of the file that you are allowed to create using a program? Has anyone else faced this issue? The file size was close to 4.3Gb(it is a bit big) when it stopped.

Answer 1

This Python bug report indicates that the OS is the source of this error message, not Python.

Since you are writing to a FAT partition, and the maximum file size limit is 4GB for FAT 32 (LinuxFilesystemsExplained) this is most likely the cause of your problem. Running your program on a system or partition with a different file system would tell you for sure.
