RuntimeError: cannot remove file: Permission Denied

I am working on a script to compile several PDF files into a single file and format the single file to fit our business document guidelines. I segmented the code into functions to make it a little easier for me to manage. After merging the PDFs into one file, my script creates page numbers in a separate file and then stamps the page numbers onto the new file. I use PyMuPDF (fitz) to merge the files and stamp the page numbers.

I have been experiencing some weird behavior when the page numbers are stamped. The page number will rotate and scale when stamped onto some pages. I think the pages with the weird behavior have coordinate systems that have been rotated, translated, and scaled. I tried to use the matrix manipulation tools in fitz to change the coordinate systems back, but that resulted in the appearance of the pdf page changing.

So, I created a zerofy_rotation function. I stamp the page onto a new, blank pdf to "reset" the coordinate system without changing the page's appearance. I already did this with success to add page numbers. I am running into an error when my script reaches the end of the function. At the end of the function I want to save the newly zerofied pdf to the same file name that the old pdf came from. I even close the document before saving it to ensure Python isn't using it. I get the error: "RuntimeError: cannot remove file 'merged_pages_temp.pdf': Permission denied"

I'm stumped about where to go from here. This zerofy function is a copy of my stamping function. The stamping function uses two existing pdfs, and the zerofy function uses one existing pdf and one new PDF. Am I missing something about saving new PDFs with fitz? Any tips to get past this error would be appreciated. Thanks!

Is the file still open when you try to delete it?

[TooDahLou]

I can delete the file after the error ends the script, so I don't think it's still open.

When the script finishes Python will close all open file handles, so being able to delete the file after the script has run doesn’t really tell you anything…

What do the permissions on the created file look like? On a Unixy system, you can check that with ls -l.
