Unable to delete css files

Hi Team,

I am creating HTML from xlsx file.
I am sucessfully able to create one subfolder containg stylesheet.css file and individual html files per sheet in it and one final html file.

afterwards I want to delete subfolder and final html file from my local pc.

but I am getting error …
“ExceptionMessage”: “The process cannot access the file ‘stylesheet.css’ because it is being used by another process.”,

though all files are closed.

how to overcome this


Thanks for your query.

Well, you only need to delete the final HTML file and the files in the sub folder will be deleted automatically.

Hope, this helps a bit.


By the way, I tried the following sample code with a template XLSX file, it works fine and the relevant sub-folder (containing the resource files) with the main HTML file are successfully removed:
Sample code:

            string filePath = "e:\\test2\\";
            Workbook wb = new Workbook(filePath + "a.xlsx");
            wb.Save(filePath + "out1.html");
            Directory.Delete(filePath + "out1_files", true);
            File.Delete(filePath + "out1.html");

Hi @Ajmad_Sahi

Even I am using the same sample code to delete files and directories.

But I am getting error at the time of deleting “out1_files”, that stylesheet.css cant be delted because it is in use


This is strange, we could not find the issue on our end. Your issue does not have any links with Aspose.Cells APIs. You may try the sample code in a console application on some different machines or restart your system to re-execute the code segment.

I am getting error as stylesheet.css is open in IIS Explorer.


The issue does not seems to be related to Aspose.Cells APIs. You may browse internet to evaluate and fix the issue, see some documents/threads for reference:

If you still think it is an issue with Aspose.Cells, kindly do create a sample project (runnable), you may zip the project (with its resource files) prior attaching here, we will check it soon.
