"Access Denied" error when trying to FTP .IGS files

I use .IGS files a lot (CAD interchange format)

for some reason, winscp comes up with "access denied"

if I change the file type to something else, no problem.

What am I missing?

Thanks!

When exactly do you get the error? Can you upload the files upload any other FTP client? Please attach a full session log file showing the problem (using the latest version of WinSCP).

Thanks for the reply.

Can't post up the FTP log because there simply isn't one, FTP server log shows everything, but nothing on this, like the event simply never happened.

if the .IGS file is in a batch, the log shows all the files before, and nothing, until you either abort or skip the file then it carries on and shows the remaining transfers.

I'm getting the impression it's winscp that can't open the file locally?

I have asked for WinSCP log, not server log.
And again, Can you upload the files upload any other FTP client?

OK,

spent more time on this, and looks like it's not a winSCP issue, it's a windows 7 problem with shared drive security.

every file in the share has the same permissions except .IGS files, looks like the win7 client PC (that winSCP is running on) identifies them as a system file and locked it's permissions.

No idea why, the work-around is to mirror the file system onto a local NAS and then FTP it from there.

Anyway, thanks for your time.

Cheers
