Transfer Deep File Paths

2011-09-27 15:48

Hi,

I did search for similar threads and saw a few reports, but nobody posted log files for you, so hopefully I can provide any logs information to help solve this problem. I did perform the initial test with an earlier version, but I just verified the issue still exists with the latest release.

WinSCP Version: 4.3.5 Build 1463
Problem After Upgrade: I don't think I've ever had deep enough file paths to encounter this before
Windows Version: Windows 7 Ultimate x64
Transfer Protocol: SFTP-3
Interface: GUI - Explorer
Error:
Can't create file
'C:\Users\XXXX\Documents\XXX\XXXX\XXXXXXXXXXXXX\XXXX\AAA_AAAA_AAAAAAAAAAAAAAAAAAA\BBBBB-3_3-BBBBBBBBBBBBBBBBBBB\XXXX-3a_XXX-3-XXXXXXXXXXXXXXXXXXX\XXX_XXXXXXXX\3a_XXXX_XXXX_XXXXX\3a_XXX-3-XXXXXXXXXXXXXXXXXXX-XXXXXXXX_XXXXX\3a_XXX-3-XXXXXXXXXXXXXXXXXXX-XXX-XXXX-X.XXX'
System Error. Code: 3.
The system cannot find the path specified
Steps to Recreate:
1) Create file path sufficiently deep
For reference, copying starting at the depth of BBBBB-3_3-BBBBBBBBBBBBBBBBBBB instead of AAA_AAAA_AAAAAAAAAAAAAAAAAAA is successful
2) In WinSCP explorer window, drag folder from remote location to desired location in windows explorer, drop folder
Software of Server: I'm not entirely clear what this would mean, but if I can get some direction/information I'm happy to try and get it

I will be emailing the log

**As the reverse: If I copy the files from deeper paths (which is successful then) and then recreate the file structure in my local copy, I can also not copy the full tree back to the remote server. It gives the same error that is given above (error code 3, can't create file)**

Well, how do you image WinSCP can handle this problem?

Maybe I'm not clear on what you mean, since it seems like the most straight-forward answer to your question would be "WinSCP can handle the problem by performing the transfer". Is that not possible?

Windows has limit of file path length. WinSCP cannot override that.

Ok, that is what I was unsure of, thanks for the information!

That's not really true

I was using TortoiseSVN on Windows and it can checkout and checkin files with long filepaths or names with no problem. Java can do the same on Windows and other applications also. I am not sure, but afaik FileZilla is also able to checkout long filepaths. Maybe the problem is not on Windows imposing that limit to WinSCP, but WinSCP depending on old Windows libraries.

WINSCP errors out: "Can't create file ..." on long names

2014-01-21 17:32

I am also effected by this issue, but WINSCP can be fixed to work around MAX_PATH by using the '//?/' file reference format. Please see https://learn.microsoft.com/en-us/windows/win32/fileio/naming-a-file#maximum-path-length-limitation

And the fix would be to map any creation of files in WINSCP to use the '//?/' prefix.

Thanks for your suggestion. I'm aware of this technique.

Still happening in 5.7.6

Hi,

I've seen WinSCP supports long paths since 5.6 (see bug #821 : https://winscp.net/tracker/821), but the issue still happens with 5.7.6. Here's the end of the log:

I use the "\\?\" notation. Do you have any idea of why it still fails ?

"Can't create file ..." on long names

2016-04-21 01:58

I have learnt that there was amount of work/discussion around file-path issues. Wondering if this has been fixed yet ? I am facing a similar issue and I am using version 5.7.6(build 5874).

XXL path problem

2016-08-25 13:03

Case description.
Local: Win 7 File System; with some XXL pathname
Remote Backup: Linux ftp server (more than 1 tested; same result)
Action: Interactive winscp sync to remote
Version: 5.9 (build 6786)
Error:
Attached

winscp builds the complete XXL directory path on the Remote Backup.
Determines that a file has to be transferred from the source.
Ok till here. But afterwards....

Solution suggestion.
Maybe that when opening the file the \\? prefix before the pathname
is not used.
