Description Simon 2016-09-20 10:45:21 UTC

I've setup a share with the vfs catia module because I have some colons in the path.

Everything works perfectly but one action : copying from windows explorer. Tried Windows 7 and Server 2008 R2.

When I try I get an error message box saying :

Item not found

Could not find this item

This is no longer located in <path with colons>. Verify the item's location and try again.

All the following works :

* Browsing with windows explorer
* Opening the files from windows explorer
* Renaming the files from windows explorer
* Copying from the cmd with "copy" or "xcopy"
* Copying empty files from windows explorer, most likely because it does not try to open the source, only creating the empty destination.
* Copying from Nautilus

Seems like when windows explorer tries to get the actual content of the file, it does so with an API that no other program uses.

Server is Samba 4.3.9 on Ubuntu 16.04.

you may not map 0x3a to a non-UTF-8 character as this is the unix charset.

Your answer makes no sense to me.

Anyway, I changed 0xf7(÷) to 0x24($) or 0x5f(_) like in the example [1], and it does not work either.

On W10, the problem does not exist.

There's something fishy going on with W7 file explorer.

As we don't have many W7 left, I will leave the issue closed, but I don't think it is invalid.

Comment 3 Björn Jacke 2018-08-30 13:25:26 UTC
the order of the vfs modules streams_xattr catia probably also needs to be the other way round.

You can try

  catia:mappings = 0x3a:0xf022

Besides that, Björn is right, catia must become before streams_xattr.
