what is the upper limit of a text file in Windows and Linux respectively?

Hi there;

what is the upper limit of a text file in Windows and Linux respectively in bytes for write? There is a limit i guess.

Say 7 and Ubuntu.

Regards.

Don't think there is a limit to the size of a text file... wouldn't really make sense for there to be one.

There can be limits to the size of a text file any given text editor can open.  A 32 bit text editor should be capped at 4 GB (or maybe even 2 GB).  But a 64 bit text editor should handle MUCH, MUCH larger.

Of course, a LARGE text file of hundreds of MB or more could take quite a while to open since most editors need to load the ENTIRE file first.  This may make them appear to have crashed (and depending on their coding, maybe they would crash).

The maximum size depends on the blocksize and filesystem type you are using.

Assuming ext3 filesystem, then the maximum file size will be between 16GB - 16TB (depending on blocksize)

It isn't the OS that defines the limits, but rather the text editor you are using. Some editors for example may need to be able to load the complete file into memory, so with such an editor you'd be limited by the amount of RAM you have available to the editor at the time you open it.

Max. file size for NTFS5 is 16 ExaBytes - max. file size for EXT4 is 16 TeraBytes

Wonder what you would do with either of those file sizes as other experts correctly mention that editing such a file would be very difficult.

My question is actually related with the read performance of those files via C# or Java.

Is there any strategy to read those in a feasible, non-crashing way?

I'm a bit lost here, first you want to know about sizes (W7 / Ubuntu), now about performance and C# / Java and about how to read a large file without crashing (crashing what btw).

What are you working on, can you post elaborate about the real question you're struggling with? I'm thinking your original question has been answered which was about max file sizes.

ah, ok updates, sorry for this delay.

i created a file in C (not C# currenlty), around 2GB.

And planning to read that file content via C# and Java. Doable in W7 and linux?

This is the actual situation.

Are you planning to read the whole file into memory or just parsing it? What is your application going to do with the file?

Hi;

It's actually parsing it. I am not using a 3rd party library to parse, just some if logic. I am planning to readt the file as a block.
AAAA
12 2.3
14 2.5
1 0.3
...
BBBB
....

until BBBB, I am planning to parse and store the numbers and AAAA.
Any best practice?

Regards.
