Number of files in a folder

Hi

Does anybody have any experience with how many files to have in a
folder without slowing SolidWorks when loading files?

We have our files in three folders called 3000000, 4000000, 5000000
and that gives a possibility to have 1000000 files in each folder.

I am thinking of creating sub-folders but have no idea when to start
(10000, 50000 or 100000 files in each folder)

Kind regards

Hi Klaus
If you use Solidworks explorer for renaming files or performing other tasks,
the larger the folder the longer you wait.
MS has a recommended size, but from what I remember, it was too small. I
would suggest between 1500 and 2000.

We limit ours to 1,000 this seems to be slow anyways. But if you limit it
any more you wil have too many folders to search. To speed up our search
for files I created a macro to take a user given part number and figure out
which directory it should be in. This way you don't have to deal with the
10,000 parts in a folder just the one and hit Open no directory hopping and
such. Much quicker. Only about 10% of the time do I have to actually
search directories and 9 out of 10 of those are R&D.

Hi
Thank you for your response. I have been searching Microsoft's
homepage but cannot find it. We have a folder with 13.000 files and I
do not find it slow. But I will talk to our IT department and maybe
they can find something.

Kind regards and have a nice weekend

access to files on NTFS partitions is weakly influenced by the directory
size (from
http://www.microsoft.com/technet/tr...prodtechnol/winxppro/reskit/prkc_fil_punq.asp) :
"
The benefit of using B-tree structures is evident when NTFS enumerates files
in a large folder. The B-tree structure allows NTFS to group, or index,
similar file names and then search only the group that contains the file,
minimizing the number of disk accesses needed to find a particular file,
especially for large folders. Because of the B-tree structure, NTFS
outperforms FAT for large folders because FAT must scan all file names in a
large folder before listing all of the files.
