Hello,

We are having OutOfMemoryException while opening 19Mb doc file and trying to save it as docx. Task manager shows spike in memory of 1.3Gb and then application crashes. I saw earlier posts on similar subject and just want to know if it still unresolved.

System.OutOfMemoryException was caught

Message="Exception of type 'System.OutOfMemoryException' was thrown."

Hi Oleg,

Your document contains > 80 EMF metafiles. They are stored compressed inside the DOC file, but when Aspose.Words reads the document into memory it uncompresses them. Some of these metafiles are really big. Total size of all of your uncompressed metafiles is > 1000 MB.

Aspose.Words uncompresses them on loading into memory.

So the only way you can open this file if you add more RAM to your machine. Aspose.Words will take loads of memory when loading the document, but when you finished processing the document, all memory will be released and garbage collected quickly. So it will be only a short spike of high memory use.

Best regards,

The issues you have found earlier (filed as WORDSNET-3449) have been fixed in this Aspose.Words for .NET 21.4 update and this Aspose.Words for Java 21.4 update.
