[BFW-5617] Wifi Based file transfer problem. about prusa-firmware-buddy HOT 4 OPEN

I am adding another example of the failed file transfer. This one 7.5mb. Transfer from Prusa Slicer 2.7.4 showed USB full error as shown in the message above. I am sending the master file and the tmp file left on the USB after the failure. Most of the tmp that exists is correct, then the end is messed up compared to the master.
The tmp file was dated AHEAD of the time shown on the printer. I think the tmp file created is dated based on GMT vs. the shown clock time on the MK4e. Would that cause a check problem? I am in Texas USA with the -6 hours from GMT set on the printer I believe.

More information. If I send the file from the PrusaSlicer to upload and run, it usually works. If the MK4 has just been rebooted or idle for a while. But almost never successful when it is just uploading the file.

Just loaded 6.0.1 for the MK4. Tested uploading files. Using PrusaLink, I did 7 uploads of various file sizes. All successful, one after another. Never got 2 in a row without failure on 6.0.0. I did a file compare of all 7 against the masters once on the thumb drive. All match 100%. It appears wifi file transfers have been improved.
Further testing shows that it still can fail. PrusaSlicer based upload fails can lead to failures with PrusaLink until a printer reboot. Seems the failures leave something hung up in the system.

PrusaSlicer 2.7.4 testing on 6.0.1 is not as reliable. Uploaded 1 file. Good, then trying to upload a 2nd file, upload only, hung the 3D printer as noted above.
After a reboot of the printer, tried again, got the USB full error. Is this still a firmware problem or related to the slicer only? I don't know.
