UnsupportedFileFormatException when loading plaintext file?

Hello there,

I just stumbled upon some problems with loading plaintext files (e.g. the one included in the attached .zip file) when trying to load them like this, particularly an UnsupportedFileFormatException is thrown:

var document = new Aspose.Words.Document(@“D:\checkouts.txt”, new LoadOptions { LoadFormat = LoadFormat.Text });

…same with no LoadOptions or LoadOptions.Auto.

This happens only with a sub-set of the plaintext files, but nevertheless is a problem. It ‘seems’ to be related to the file’s encoding/format but as a user of your API, I really didn’t expect any such problems nowadays, particularly no matter what the encoding is, the file should load just fine.

The minimum would be a more meaningful exception that I can handle properly as the exception / its message provides no indication for the developer, nor the user to handle it.

Is this a known issue & will be fixed - or even better, known and solved?

Best regards and thanks,

Hi Tahir,

thanks for the quick reply & ticket creation. Is there any eta for these kind of issues? This is currently a show stopper for us as we do have lots of these files.

Hi Joerg,

Thanks for your inquiry. I have verified the status of this issue from our issue tracking system and like to share with you that this issue is under review. Hopefully, the fix of this issue will be available in next release of Aspose.Words.

We appreciate your patience.


according to the link right next to my inital post it says the issue was ‘Resolved’. I was wondering whether that particular version (which is it?) is already available and if so, how it was ‘Resolved’ - as in, are plaintext files now supported no matter what encoding or is there any other way of handling these?

Currently we get a message saying ‘WARNING: the attached text file could not be read because its encoding could not be determined!

… which is not really a useful indicator for our users - as in… what would they be supposed to do now (what encodings ARE supported etc)?
