FTP uploads to incorrect directories with parallel upload

Post "TC8.0 bug" and "TC8.5 bug" joined:

Only after posting for 8.01 I noticed I'm using an old version of TC. However, the bug also applies to 8.51a (64bit):

I have two directories, "1" and "2":

\1\A\A1.txt
\1\A\A2.txt
\1\A\A3.txt
\1\A\A4.txt
\1\A\A5.txt
\1\A\A6.txt
\1\A\A7.txt
\1\A\A8.txt
\2\X\X1.txt
\2\X\X2.txt
\2\X\X3.txt
\2\X\X4.txt
\2\X\X5.txt
\2\X\X6.txt
\2\X\X7.txt
\2\X\X8.txt

I FTP upload "1" in the background. While the upload is running, I start uploading "2" in the foreground.

When both uploads are finished, I have the following directory structure on the FTP site:

\1
\X8.txt
\1\A
\1\A\2
\1\A\A1.txt
\1\A\A2.txt
\1\A\2\X
\1\A\2\X\A3.txt
\1\A\2\X\A4.txt
\1\A\2\X\A5.txt
\1\A\2\X\A6.txt
\1\A\2\X\A7.txt
\1\A\2\X\A8.txt
\1\A\2\X\X1.txt
\1\A\2\X\X2.txt
\1\A\2\X\X3.txt
\1\A\2\X\X4.txt
\1\A\2\X\X5.txt
\1\A\2\X\X6.txt
\1\A\2\X\X7.txt

Total Commander's FTP protocol shows it's not a problem of the FTP server, but that the upload itself was mangled:

I have just tried this with uploading to ghisler.com, but it all worked correctly. It sounds like your server is maintaining only one current directory for all sessions. This would confuse TC because it works with uploads to current directory, not uploads to full path.

Thank you for the quick reply. Yes, I can confirm it - it was a pecularity of the FTP server, and not a bug of Total Commander.
