Thanks for your inquiry.
1. Can a file after conversion be taken in a variable before being saved to the disk
You can save the output file in memory stream. Please check the overloaded Document.Save methods from here:http://www.aspose.com/docs/display/wordsnet/Save+Method
Specifically converting doc/ pdf /txt/ rtf / docx to HTML
You can convert Doc, Docx, Rtf etc files to HTML file format by using Aspose.Words. You can load file
formats mentioned at following documentation link into Aspose.Words DOM.http://www.aspose.com/docs/display/wordsnet/LoadFormat+Enumeration
Once you have loaded a file of LoadFormat
into Aspose.Words DOM, you can easily convert it to HTML.
2. Aspose works on specific formats . What is the method suggested to conform the mime type of a file before using it in a appropriate converting module.
It would be great if you please share some more detail about this query.
Please check the SaveFormat
enumeration from here: http://www.aspose.com/docs/display/wordsnet/SaveFormat+Enumeration
SaveFormat indicates the format in which the document is saved. If save format is invalid, Document.Save method throws ‘Invalid save format requested
3. Is there a generic method which could auto detect file type and convert accordingly.
constructor automatically detects the file format. You need to load the document of LoadFormat into Aspose.Words.Document and save it by using Document.Save method.
