Hello, here is my code open(filename, "w+") do io C = Mmap.mmap(io, BitArray, (64,10^3)); BinX = getHash(r.x) for p=1:length(BinX) C[p, 1] = parse(Int, BinX[p]) end Mmap.sync!(C); end After I try to open or delete the created file, but I receive a message that the file is occu…

Most likely, C hasn’t been garbage collected. First make sure you’re not storing the return value somewhere (the fact that you need that semicolon means this block returns C to the caller). Then try calling GC.gc().

[image] tim.holy: GC.gc() . I tried GC.gc (), but the result is the same, with the exception of performance degradation.

I’m not entirely sure whether this works, but you could also try to call finalize(C) after the Mmap.sync!(C); call.

A runnable example might help (your example references lots of variables that we don’t have). Also details about your platform: Windows is quite different from Linux, for example.
