Also, this time there were no problems copying files.

Since you asked for session log, I didn't have it. So I redownloaded WinSCP emailed version and repeated exact steps. Updated trace file and session log sent to email. First file is session log. 39 compressed files, 528MB.

I emailed you (Martin) all compressed (ZIP) logs.

Sorry for late reply. There are 24 x 1GB 'trace log' files and 1 x 70.7MB file. Which to upload?

What I did:
- Turned on Ras Pi, waited for main menu > turned off power savings.

- Opened WinSCP (emailed version) > typed in Hostname/Username/Password, Login.

- (WinSCP) Browsed to:
/<root>/userdata/roms/psx/

- Dragged-and-dropped these files, one at a time (no problems):

- I closed WinSCP. Above I mentioned that Ras Pi's power savings are disabled. I restarted Ras Pi to all it to 'reinitialize', then updated gamelists, then checked free space. used 17.75GB/25.89GB (free 8.14GB).

Thanks. I have sent you a new debug build.

• Perhaps the issue is long Ethernet cable or Batocera, not WinSCP. Perhaps lookup network file transfer timeout length in Batocera's documentation (Batocera version BCM2836-36-20230311 For Ras Pi 2).
  
• ROMs were copied one-at-a time. Hopefully there won't be problems if copied all at once in same copy session.
  

• (Ras Pi) started to main menu.
  
• Opened "WinSCP-20240220r_master_6.3.1_2ecd6c615-Portable".
  
• Logged into Ras Pi (SFTP, Port 22).

Log file (compressed 26.6MB, extracted 411MB):
<invalid hyperlink removed by admin>

I'm sending you an email with a development version of WinSCP.

• Turned on Ras Pi.
  
• (Ras Pi) turned off power saving.
  
• Opened "WinSCP-20240216doleg-Portable" (latest emailed version, same extracted copy as used for emailed Trace Files).
  
• Enabled Debug 1 logging.
  
• Logged into Ras Pi (SFTP).
  
• Browsed to:
  /userdata/roms/psx
  
• Opened Explorer > browsed to PS1 ROMs location.
  
• Dragged-and-dropped "Crash Bandicoot - Warped (1998).bin" into WinSCP.
  
• It mostly copied, then this error appeared:
  "Bad message (badly formatted packet or protocol incompatibility).
  Error code: 5
  Error message from server (en): badly encoded SFTP packet"
  > Retry x3 > Abort.
  
• Tried copying other files, same error every time.
  

---

• Copied files (all ending with ".filepart"):
  

  Crash Bandicoot - Warped (1998).bin
  
  Crash Bandicoot (1996).ccd
  
  Crash Bandicoot (1996).img
  
  Crash Bandicoot 2 - Cortex Strikes Back (1997).bin
  
  Crash Bash (2000).bin
  
  Crash Team Racing (1999).bin

  
  
• Debug 1 log + new Trace File:
  <invalid hyperlink removed by admin>
  

Possibly this issue:
Issue 2259 – Badly encoded SFTP packet when renaming a file using SFTP version 5 and newer
But I need the logs to be sure.

• Old version log emailed.
  
• New version log emailed.
  
• I'm strongly considering using Live Linux to copy-paste those Roms into Batocera's EXT4 partition. Must be far easier than all this.
  

[COPY OF EMAIL, EXCLUDING LOGS HERE]
OLD VERSION (6.1.2.13797, above):

• I disabled power saving on Ras Pi. No change.
  

I tried copying 1 file at a time. Some copied fine, others showed errors for these actions:
Copying Spyro 2: Ripto's Rage
Copying Spyro The Dragon
Copying Street Fighter EX Plus Alpha
Copying Street Fighter EX2 Plus

I then restarted Ras Pi to see if that would fix anything. Only 4 of 41 files show up in Batocera's EmulationStation interface, after restarting and updating gamelists. Of those 41 files, 18 were games, other files were extra tracks. Maybe a problem with Batocera itself. There were 13 other files to be copied, but I replaced WinSCP with Debug (emailed) version, and didn't get a chance.

NEW VERSION (WinSCP-20240213d_master_6.2.5_2eaa691b6-Portable):

• Ras Pi power saving is disabled.
  
  
  
  • Uninstalled old version.
    
  • Turned on Ras Pi (boot to main screen).
    
  • Extracted 'portable' new version to Desktop > opened it.
    
  • Typed in "host name" (IP address, Username, Password) > Login > Accept (connection).
    
  • Browsed to "/<root>/userdata/roms/psx" > deleted all files to replicate issue.
    
  • Opened Explorer > browsed to PS1 roms location (to copy from).
    
  • (Ras Pi) checked space remaining: 14.35GB. PS1 rom are 13.6GB. More than enough space. 768MB should remain.
    
  • (WinSCP) changed settings to reconnect every 1 second (on each disconnect), to save time.
    [View > Preferences > Transfer > Endurance > Enable transfer... - All files, 1 second selected for next 3 commands.]
    
  • (Explorer) Ctrl + A (all rom files) > drag and dropped into WinSCP > (file transfer dialog) OK. 54 files, 13.6GB.
    
  
  
• Within 1 minute, error appeared:
  "Assertion failed: FPacketReservations -> Items[i] == NULL, file core\SftpFileSystem.cpp, line 1982"
  
  
  
  • OK > error appeared "Abnormal program termination".
    
  • WinSCP crashed/automatically closed itself. Not able/don't know how to create 'Session Log'. Trace file attached.
    
  
  

ALL PS1 ROM FILES (54 files, 13.6GB):

Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

I manually restarted between 13 roms and 41 roms.

Pr:
Stack Trace error when copying from Explorer to WinSCP session (SFTP, pre-saved, GUI, Explorer interface).

TASK:
Copying many PS1 roms from computer to Ras Pi 2 Model B V1.1, "Batocera Linux BCM2836-36-20230311" for Ras Pi 2. WinSCP was set to continue copying every 1 second, regardless of disconnection (most likely caused by extra-long Ethernet cable; I don't have WiFi USB Adapter yet).

WHAT I DID:
Turn on PC, turn on Ras Pi, (Ras Pi) open Main Menu, (PC) open WinSCP, open Windows Explorer, auto-connect to pre-saved SFTP (default) protocol, (WinSCP) browse to "/roms/psx/", (Explorer) browse to PS1 roms, drag-and-drop many roms (54, including duplicates for tracks), (WinSCP) starts copying. After a while, this error shows up. It didn't when I was only copying "13" roms (finished very slowly, no issue, set speed is at Unlimited), (Ras Pi) restarted. But did when trying to copy remaining "41" roms.
