Which file system can I use to over come it? >I am planning for JFS >Does anybody has any recommendations? ext4 is unlimited. http://en.wikipedia.org/wiki/Ext4 is wrong in the section "Break 32,000 subdirectory limit". SOmeone should correct it, because https://ext4.wiki.kernel.org/index.php/Ext4_Howto#Sub_directory_scalability clearly tells " Ext4 breaks that limit and allows unlimited number of sub directories". There is also an ext3 -> ext4 howto in the same page I gave above. -- Architecte Informatique chez Blueline/Gulfsat: Administration Systeme, Recherche & Developpement +261 34 29 155 34 / +261 33 11 207 36 -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

Is Wikipedia ext3 article¹ wrong then? :-? *** Limits Max number of files Variable, allocated at creation time[1] [1] The maximum number of inodes (and hence the maximum number of files and directories) is set when the file system is created. If V is the volume size in bytes, then the default number of inodes is given by V/213 (or the number of blocks, whichever is less), and the minimum by V/223. The default was deemed sufficient for most applications. The max number of subdirectories in one directory is fixed to 32000. *** Note that "The max number of subdirectories in one directory is fixed to 32000." ¹ http://en.wikipedia.org/wiki/Ext3 Greetings, -- Camaleón -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

Oh... sure? ;-) > English can be a pain when it is not your first language - and, come to > that, even if it is. ;-) Well, I admit my English is not the very best it could be, but for sure the OP concern was "32000 files/folders under a folder" and if I read ^^^^^^^^^^^^^^^^^^^^^^ that in a correctly manner, it says something about *folders under a folder*... I hope "subdirectories = folders" is still valid. :-) Greetings, -- Camaleón -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?

No offence taken :-) I know "folder" is very much used in windows environments (and also by newbies) and "directory" is a more correct term, widely used by "techies". > Which raises the question of - why the inconsistent results?? ;-) What "inconsistent results" are you referring to? You mean the divergence in the answers the OP is getting? :-? Greetings, -- Camaleón -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?
