You need both copies, even if they are duplicates. In fact, you may have two identical, duplicate copies of STATS.DLL.īut deleting either one would be a big mistake: deleting A’s copy would break A and deleting B’s copy would break B. You have two copies of STATS.DLL on your machine. When A is updated, it only updates its copy of STATS.DLL. Later, installing B does the same, placing a second copy of STATS.DLL for only B to use. Installing A places STATS.DLL into a private location where only A can use it. If B breaks because of this unexpected update, you’re stuck until B is updated to work with the newer STATS.DLL.
Put another way, an update to A that includes an update to STATS.DLL updates it for B whether or not B needs it, wants it, or B works with the new version. Updating STATS.DLL updates it for both programs A and B. Sounds fantastic, since disk space is saved and there’s only one STATS.DLL to keep track of.
WHEN I DOWNLOAD SERUM I ONLY GET .DLL FILES INSTALL
When you install B sometime later, it sees STATS.DLL is already present, and does not install it a second time. Installing A installs STATS.DLL such that any other program can use it. Program “A.EXE” (A) and program “B.EXE” (B) both rely on a large library of mathematical functions we’ll say are contained in the file “STATS. Over the years, software programs have gone from attempting to share large numbers of components to keeping separate copies of those components to protect themselves from unexpected changes.Īs a result, today some files are shared and some are not, and there’s no consistent rule. You’re best served using different techniques if you’re running low on space. Duplicates rarely take up excessive room. Sometimes you can delete duplicates safely, but it requires knowing how your files are organized - something duplicate file finders can’t do. Because installing software in Windows is complex, it’s common to have duplicate copies of the same file, all of which are required.
