Free space not available

[yan74s]

Hello

I have transfered Sets of Roms from an USB stick to my SD card. (created the /share/ folder structure on my stick to simplify the copy by "cp -rv /media/usb0/share /recalbox/" )
But there where too much data on my USB stick and my SD card were filled at 100% (last files were writed with the size of 0 octet)

After that, under windows, with access to my raspberry trough my network, I deleted all the 0 octet files and some other big files to free some space .

But I have this problem :
I made free space (I can see free space with PartionGuru) but if I try to copy files Windows says that the folder is still full.

What happens under command line : (I wrote only the line with the problem, the others are ok)

df -h
Filesystem ....................Size...............Used..............Avail...............Use%...............Mounted on
/dev/mmcblk0p8...........55G..............50G..................0...................100%............./recalbox/share

As you can see see : I have 5G of free space but it says 100% use and 0 available
(Before I deleted some files trough windows, I had 0G of free space)

Is there a way to refresh the memory ? Or a way to get back my free space ?

Thanks in advance for your help !!

I will not helping a lot but I have same kind of issue:

df -h
Filesystem Size Used Available Use% Mounted on
/dev/mmcblk0p3 114.9G 110.7G 0 100% /recalbox/share

It seems that it's happening when I remove files from WinSCP or Putty for exemple (I find it easier when I have to remove a directory like in Dosbox emulator)

I have searched on the web for refreshing this lost free space but everithing I can find is tutorials on how to find the dummy/trash/lost files...
Not a big deal because I can still copying games on the card, but updates are crashing because of the "lack" of free space

This reminds me something, but i just can't remember what was the origin of the problem ... Any trashbin folder or lost files or something like that ?

I met the worries. I solved it. I'm posting this to help someone: It's related to the super user placeholder. By default on ext4, it is 5%. To recover this space, you must mount the key on a linux distribution and use tune2fs on the "Share" partition. Like this: tune2fs -m 0 / dev / sdXY. You will recover the few remaining GB.
