I got this crash when using the MediaAudio2 (v. 1.4) plugin to copy a Samsung, backup from the SD-card on my Samsung Galaxy S20, Android 13 to my Windows 7 PC.
I also get a crash in the 64bit version, but get no crash report.
The report above I got after the first file was tried copied.
I also got this report after an almost complete copy og the same dir (4.8 Gb in 591 files)

Re: [TC 10.50 ] Crash in when copying with MediaAudio2

I have a Samsung Galaxy S10e, and MediaAudio2 works just fine. It only has Android 12, though, and will not receive Android 13. So maybe Android 13 is sending some invalid data which the plugin can't handle - we will unfortunately never know.

It only occurs if I mark the entire folder (in this case called 1670454987192), and it appears to happen when TC get to the file SmartSwitchBackupinf.bk in the root of tat folder. If I exclude SmartSwitchBackupinf.bk from the copy process (Only files of this type: *.* | SmartSwitchBackupInf.bk) then it works OK. The same if I go into the 1670454987192 folder, mark all the folders and files and start the copy.
the 1670454987192 folder is located in the SmartSwitchBackup folder on the SD card.
When testing this, I came upon this:

Where on your phone is that folder "1670454987192" located? Is it some kind of system folder? It's quite unusual to have a folder with so many digits.

It is placed on my SD-card in /storage/3135-6464/SmartSwitchBackup (when I enter my SD-card from the front page - SmartSwitchBackup is in the 1'st level (just like for example DCIM)
The number, I guess, is the Unix time in milliseconds

I see, so is there anything special about that file SmartSwitchBackupInf.bk? Maybe it's larger than 2GB or even 4GB? These are both special limits, the first is the maximum for a 32-bit signed size, and the second the maximum for 32-bit unsigned (actually 4GB-1 byte).

It is an ANSi text-file with this content:
Code: Select all
{"backup_id":801751359,"device_name":"SM-G981B","display_name":"Samsung Galaxy S20 G5","date":"1670454987192","size":8393001780}
one line only, no line-break.
in the root of the 1670454987192 folder there are these 5 files:
.nomedia
SmartSwitchBackup.bk
SmartSwitchBackup.bk_backup
SmartSwitchBackupInf.bk
SmartSwitchBackupInf.bk_backup
the SmartSwitchBackup.bk and SmartSwitchBackup.bk_backup are 1.9 Mb binary files, the rest are ANSI text files below 130 bytes. And then there are 62 subfolders, but TC doesn't even get to copy those.
I now tried again - excluding the SmartSwitchBackupInf.bk file (Only files of this type: *.* | SmartSwitchBackupInf.bk), but the TC just crached when trying to copy the .nomedia file.
If I try to use the Synchronization Tool to copy the 1670454987192 directory TC also crashes.
When I reopen TC after the crash I can see a 0 byte SmartSwitchBackupInf.bk file and nothing else in the 1670454987192 folder on the PC.

Do other file operations like renaming these files work without crash? With Android 12 I have the strange behaviour that renaming returns an error, but when I then refresh the list, the name has actually changed.

Look at the size: 8393001780. It's almost 8 GiB.

The size is 128 bytes - what you see in the code box here above.

If I try to rename any file with MediaAudio 2,I get a message that it is not possible - remove the write protecyion. When I afterwards reload the folder, the file turns out to have been renamed anyway.
If I try to open SmartSwitchBackupInf.bk in Lister I get the same crash as when I try to copy it.
But I have testet a lot and have so far found out that it does not depend on the filename or the folder name, but in some way depends on the size of the file.
Here is what I do to reproduce the bug:
1. Download this archive:
https://madsenworld.dk/tcmd/test.zip
2. Copy the 3 files in the archive to any directory on the phone (for example Documents on the SD-card)
3. Close and reopen TC, and open the phone's SD-card with AudioMedia 2 and go to the Documents folder
4. Copy the file test2.txt to the PC - no problem here
5. Copy the file test1.txt to the PC - TC crashes here
6. Reopen TC and copy the file test3.txt to the PC - TC crashes here
So it not just the size of the file. And it is not whether it has line breaks (I have tried that too), it is just som (small) sizes of non-binary files that causes it.

Peter, this small file contains info about total backup size. Is it so difficult to understand it?

It is only that little file that is not copied and causes the crash, the rest of the backup copies fine - the backup is NOT one big file, it is 591 files in 62 folders. The biggest file is 176 Mb an the total backup is 4.7 Gb
Also read my next post - it is not about this particular backup, it happens when ever I try to copy small ANSI files of certain sizes, from anywhere on the phone.

So it's larger than 4 GiB, and the number in
"size":8393001780 is probably a total size of UNPACKED set of files.
It looks like a bug in a backup tool - it can create a backup set larger than 4 GiB, but it cannot UPDATE it (If I understand it correctly, this small file is added as the last one, when the backup is finished). Have you tried to create a backup set smaller than 4 GiB?

It is not about the backup, it was just here that I first experienced the bug - please read the other posts here above especially:
