COSnet - Cannot extract CLIP_RN101_49 features

[assafbk]

Hi,
The features of CLIP_RN101_49 are saved as 4 files (in https://drive.google.com/drive/folders/12WbB3VkJh0NB9b8xlflY3PxTM3BwHtnF) .

I tried to concatenate them and then untar:

cat CLIP_RN101_49.tar.001 CLIP_RN101_49.tar.002 CLIP_RN101_49.tar.003 CLIP_RN101_49.tar.004 > CLIP_RN101_49.tar
tar xf CLIP_RN101_49.tar

but the result of this is a .zip file
i try to unzip with this command:

unzip CLIP_RN101_49.zip

and get the following error:

Archive:  CLIP_RN101_49.zip
warning [CLIP_RN101_49.zip]:  10502549372 extra bytes at beginning or within zipfile (attempting to process anyway)
error [CLIP_RN101_49.zip]:  start of central directory not found;  zipfile corrupt. (please check that you have transferred or created the zipfile in the appropriate BINARY mode and that you have compiled UnZip properly)

Is there something that I am doing wrong?
Thanks in advance
