cut & paste on external sd-card

[fre78]

Hi,

When I cut a file from my (external) SD-card and paste it to another directory on the same (external) SD-card, normally such operation should be finished in a couple of seconds. It's actually the same as moving a file on the same disk.
But on my device (T810, lollipop 5.0.2) when I do such a cut / paste operation (from external SD to another directory on the same external SD), it first copies this file to the other directory (which takes a very long time when it is a large file) and then it deletes the original file. It happens with different file managers (ES file explorer, solid explorer, total commander).

When using the stock file manager ("my files"), the cut / paste operation happens as it should: just a couple of seconds for a large file. (I suppose just the reference to the file is changed, not the whole file itself is copied to another location).

I'm wondering why non-stock file managers needs so much time for a cut/paste operation, and why the stock file manager just needs 2 seconds for the same cut / paste operation? Is there something I can do so that the non-stock file managers can handle such a move operation more efficiently?

Only the people who wrote the file managers can tell you why they chose to use copy/paste/delete rather than mv. (It could be because if an mv operation blows up you lose the file, if a copy/paste/delete blows up, you always have the original. I always do it manually that way myself.)

I doubt, with the level of sophistication in ES, that they don't know the mv command.

What is weird is that this behaviour is totally different on my rooted phone (samsung S3 - archidroid Kitkat): cut/paste from/to the external SD-card only takes 2 seconds for big files with ES file explorer, solid explorer...

Also, when doing a cut/paste on the internal sd on my S2 tab, it does its job very fast: here it is clear that only the reference is changed, and that the file itself is not copied.

Maybe it is a matter of root. If I should root my S2 maybe the cut/paste operation on the external sd-card goes as efficiently as on the internal sd-card (or as on my rooted phone). At the moment, I do not want to root yet because of warranty issue...

Problem solved: it's a matter of root.
When rooted, cut/paste = move (=fast)
When unrooted, cut/paste = copy and delete (=slow)
