FTP from win10 PC to TSO/ISPF

Reported by: JY Owned by:
Priority: normal Component: FileZilla Client
Keywords: B37 Cc:
Component version: Operating system type: Windows
Operating system version:


FZ version
I enter a custom command "site tracks pri=300 sec=30" to overwrite the z/OS default size allocation but the site tracks pri=300 sec=30 is not taken. The Z/OS file get allocate to the z/os default size of 15 tracks which is not enough to hold the PC file (11.7MB). once the z/os file get full then FZ start looping

From the log:
Command: PASV
Response: 227 Entering Passive Mode (x,x,x,50,21,72)
Response: 125 Appending to data set FJ09.INSTALL.CD.FILES.INSTALL
Response: 451-System completion code and reason: B37-04
Response: 451-Data set is out of space.
Response: 451 Transfer aborted due to file error.
Error: File transfer failed after transferring 1024.0 KiB in 1 second
Status: Starting upload of D:\FTP\R6501.ML005\MVS\FILE\INSTALL
Status: Retrieving directory listing of "'FJ09.INSTALL.CD.FILES.'"...
Command: PASV

I know the error
451-System completion code and reason: B37-04
is because the z/os file is full.
my problem is "why FZ did not take the custom command?"
Site tracks pri=300 sec=30 when I get the response of accepted.

From the log:
Command: site tracks pri=300 sec=30
Response: 200 SITE command was accepted

I you need other details, let me know.

Custom commands are sent over the browsing connection. If your command does not affect the global server state, it has absolutely no impact on the transfer connections.

If these commands are only session-specific, have a look at

Quite frankly, you should ask your server administrator or server hosting provider to switch to a more modern server. If that doesn't help, switch to a different server provider instead.
