Question: User: do i add the deleted files or subtract them
1. The question is whether to add or subtract deleted files in a calculation.
2. Typically, when dealing with files or quantities, deleted files represent a reduction in the total count.
3. Therefore, you should subtract the number of deleted files from the total number of files.
4. For example, if you start with $T$ files and delete $D$ files, the remaining files are calculated as:
$$\text{Remaining files} = T - D$$
5. This subtraction reflects the decrease caused by deleting files.
6. So, always subtract deleted files rather than add them when calculating totals.
