max length filename

I understand the maximum length for a filename in Windows is 256 ... true ?

 

Is there any way around this ? Certainly people have need for apps that

use longer filenames, no ?

 

Any shells for Windows that somehow get around this problem ?

AFAIR, the limit is 260 characters. Some utilities (e.g. robocopy) are not

subject to it. I'm not aware of any shells that get around it.

You made me curious, so I ran a quick test. Here is the longest folder+file

name I managed to create:

D:\aaaaaaaaaabbbbbbbbbbcccc0\aaaaaaaaaabbbbbbbbbbcccc1\aaaaaaaaaabbbbbbbbbbcccc2\aaaaaaaaaabbbbbbbbbbcccc3\aaaaaaaaaabbbbbbbbbbcccc4\aaaaaaaaaabbbbbbbbbbcccc5\aaaaaaaaaabbbbbbbbbbcccc6\aaaaaaaaaabbbbbbbbbbcccc7\aaaaaaaaaabbbbbbbbbbcccc8\123456789012345678.txt

It's 259 characters long.

So , like I said , the max length for a filename alone is 256 ...

Re: max length filename

 

Well no, it's 255. .txt is four characters.

Re: max length filename

 

Heh ...

 

I am interested in the max filename length including any suffix.

 

I don't think it's reasonable to not include the suffix in the length --

there is no requirement that a filename include a suffix.

 

My tests show that :

 

filename max length = 256

 

filepath max length = 259
