is there any space limit in ascii files???

Hello everyone!

I would like to ask if there is a space limit for ascii files in python.

For some reason I am writing some data in an ascii file and while everything seems to be ok... suddenly the code crashes and an error appears saying that something goes wrong with the delimiter "w+"

Do you have any idea why???

Files are not limited by size except by the amount of memory on your machine or memory the OS can handle, and not always by that, depending on what you are doing with it. Post the error message and maybe we can help further.

This is the error that comes out:

IOError: [Errno 22] invalid mode ('w+') or filename: 'test.asc'

Thank you very much...

I would like to add something

When running the same code in a smaller grid (4x5) everything is ok!!! The problems appears in the big grid (300 x 300).

I have changed the file extension from "asc" to "ascii" and everything is running!!!

But unfortunately another problem comes up.

I need to convert this "ascii" file into raster and when I am using the command "arcpy.ASCIIToRaster_conversion" there is no way to use a file with the extension "ascii"... The file must have an "asc" extension. Why? Which is the difference between these two extensions?

try renaming it to "filename.txt", or "filename.asc".
