Hi All,

This weekend I'm in the process of moving a fileserver to new hardware and
currently in the process of having to manually copy a large number of files
over instead of utilising xcopy. This is because xcopy failed to copy a
number of files because of the path length limit of 256 characters is broken
by some files. Xcopy error message just says “Access Denied”.

This has happened because our main file server structure is built utilising
a map drive h:\ to the actual department and sections folder on our main file
server e.g.

Map H:\ to D:\fileserver\department One\Section One
Map H:\ to D:\fileserver\Department Two\Section Two

This give the user extra characters before windows prompts the user that the
file you have named is over the 256 limit. This is fine until the
administrator needs to copy the fileserver to a new location and is locked
out of the file because of the limit.
When I browse to the physical location of the file on the server
“D:\fileserver\...........load of paths\file path of this file is over
256.doc” for example you can't right click and properties but the file is
physically available.

I spend an hour thinking it was permissions and once take ownership didn't
work copied the offending files to a folder on the root of d:\ and all worked
fine. Any idea of how to get xcopy or another utility to copy folders and
files over the 256 path limit.

I am currently mapping within the fileserver like our H:\ drive works to
copy the files over but seeing this issue coming up again in the future.

Any ideas of advise, we currently have been through a restructure so is a
perfect time to modify they way this works but have a g:\ drive mapped to the
root of our fileserver that always users to browse to other sections folders
if they have access.

Thanks
Richard

Hi Richard,

Thanks for posting here.

There is a workaround for your scenario. For more information, you may
refer to the following Microsoft Web site:

Cannot access folder because the path is too long or deep
http://support.microsoft.com/kb/180410

I also copy related information as below just for your convenience:

WORKAROUND
==================
To work around this issue, you can use the SUBST command to associate a
drive letter with the long path to access the file or folder. To do so,
follow these steps: 1. At a command prompt, change to the parent folder
that contains the file or folder that you are trying to use.
2. To assign a drive letter to the location, type subst drive . , where
drive is an available drive letter and "." is a period, indicating the
current folder.
3. Type exit , and then press ENTER.
Note You can remove the virtual drive letter by typing subst drive : /d at
a command prompt.

You can also work around this issue by connecting recursively to the share
on the server and using a drive letter to point to the share.

The hotfix in above KB is applied for Windows 2000. As far as I know,
there is not a hotfix of this issue for Windows 2003 Server.

Hope this helps.

Have a nice day!

thanks for this, filed away for future reference.

In the end I used veritas to make a back and restored the files that was
missing.

Thanks

Hi All,

This weekend I'm in the process of moving a fileserver to new hardware
and
currently in the process of having to manually copy a large number of
files
over instead of utilising xcopy. This is because xcopy failed to copy a
number of files because of the path length limit of 256 characters is
broken
by some files. Xcopy error message just says “Access

This has happened because our main file server structure is built

Map H:\ to D:\fileserver\Department Two\Section Two

This give the user extra characters before windows prompts the user
that
the

administrator needs to copy the fileserver to a new location and is
locked
out of the file because of the limit.
When I browse to the physical location of the file on the server
“D:\fileserver\...........load of paths\file path of this file is

256.doc” for example you can't right click and properties but the
file

I spend an hour thinking it was permissions and once take ownership
didn't
work copied the offending files to a folder on the root of d:\ and all
worked
fine. Any idea of how to get xcopy or another utility to copy folders
and
files over the 256 path limit.

I am currently mapping within the fileserver like our H:\ drive works
to
copy the files over but seeing this issue coming up again in the future.

Any ideas of advise, we currently have been through a restructure so is
a
perfect time to modify they way this works but have a g:\ drive mapped
to
the
root of our fileserver that always users to browse to other sections
folders
if they have access.
