Copy - filename confusion (short/long?)

[xerces8]

Hi!

Using TC v7.56a on Windows 7 Professional 64 bit (all updates) I encountered this issue while copying:

- I dragged a folder from left pane to right (there was an empty folder) and TC started to copy
- after a while an overwrite dialog popped up

The dialog asked about overwiting a file named STR~1 (file length 5550 bytes) in the destination folder with a same named file from the source folder (length 10 bytes).

Checking both folders by DIR /A shows:

source folder:

Code: Select all

C:\Windows\system32>dir  /a "C:\tc\2011-2012\Sinteza procesov\natasa\Prosyn\Win\ProGraph\structur"
 Volume in drive C is Win7ProSP1_64bit
 Volume Serial Number is 5E18-F90D

So it seems, the files .str and STR~1 were somehow confused.
Is this a bug?
In TC? Windows?

I also have a screenshot of the dialog, I can post it when I remember how to do that on this forum.

PS: While previewing this post before posting, I get all backslashes replaced by a W with a strike through in the CODE parts. (I put one here to see if it is also affected: \ Nope, here is stays a backslash. I use currently IE9.)

PPS: Both volumes are NTFS.

It also happens using other tools (Explorer, XCOPY, CygWin cp), so it seems it is some "gem" left over in Windows from ancient times...

The problem is the name

.str

, which is an invalid name in DOS. Windows therefore creates an alternate DOS name STR~1 for this file.
