I have the following code:

In nodejs, how do I overwrite a section of a file without creating additional files or reading all the data into memory?

For the below posted code in section code-1, I extract the contents of .tar file to a specific path. Then I want to rename the the extracted files as shown in the code.
The number of extracted files are six, and I can see them listed in the vs-code project explorer.
The propblem i am having is, the exectuion of the code of .on('finish') is faster than the process of extraction of the compressed files of the tar. At run time, all the renaming processes are completed except the last one mentioned in the code, despite the
project explorer of vs-code shows that the extracted file with name SysConstants.CONST_BAND_5_NAME.description is listed.

I make RESTAPI call to an endpoint, and I expect to receive .tar contents. But what i received is

Using NodeJS, I am setting a code to save a string in a file where it can be retrieved from later. Instead of the string being saved, I receive an error message saying that the file system is read-only. This seems strange because in tutorial examples, the file is created if it doesn’t exist, and the data is written. So, I’d like to understand how my desired outcome could be achieved.
