Crash with large files?

I have noticed a problem which I think occurs with files larger than 2GB. At the end of the download, after all connections have been closed but before the file is renamed from *.mass, I get an access violation message. ("Access violation at address 0048AF8A in module `massdown.exe`. Read of address 00C00000.") The Mass Downloader GUI does not go away after clicking OK.

If I try to continue the download, it tells me that the download is complete. But the file is still named *.mass, and I can`t get the program to fix the name. Attempting to remove the entry from the projects list and re-add it (by any means) results in the download restarting.

1) How can I get the existing download renamed and adjusted to its correct size?
2) Can you fix it so the problem does not occur?
3) How can I be sure that the file downloaded properly (i.e., that bytes with offset >2GB were downloaded properly)?

Thanks.

Dear Keith Mason,

Thank you for your report.

> 1) How can I get the existing download renamed and adjusted to its correct size?

Could you please try to remove the .Mass addition from the file name using any file manager?

> 2) Can you fix it so the problem does not occur?

Yes, of course, we will try to reproduce this problem and fix its cause ASAP. Could you please give us the link of this file for a test? Also, what is the free disk space amount at your download destination disk?

> 3) How can I be sure that the file downloaded properly (i.e., that bytes with offset >2GB were downloaded properly)?

I think that this file is downloaded correctly. The error has happened on the last stage, when Mass Downloader was renaming it (the possible cause is the low memory or disk space.) Please try to rename this file by removing the .Mass addition.

This does not adjust the size of the file. The size of the original file is 2,411,724,800 bytes. The size of the .Mass file is 2,411,728,896 (an increase of 4,096 bytes).

I don`t want to give the link publicly because it`s on my home computer. I will e-mail the link and a password to you separately. What address should I send to?

The disk available is 10GB, and the RAM available is 150MB. Also, I have been downloading 3-4 1.5GB files at a time without a problem. It is just the 2.2 GB file that is failing.

This will not affect most file types. Please remove the .Mass addition and test the file.

I have sent you a separate email.

Thank you for this information.
