What is different with these files in comparison to others where the modifications can be written?
The checking programs in the already supplied links do help, believe me.
If the files are OK, then it could be that another program accesses the files at the same time and blocks them.
You still have to investigate locally. Or try to supply a file if the problem occurs always with the same file.
