zip file is told to be correct. can't extract by unzip. i think because such a large file is not supported by unzip. it's a 34GB file. is there a way?

zip

hamidi

i tried the command line unzip. i get the following: file #66350: bad zipfile offset (lseek): 38631718912 and file #65841: bad zipfile offset (local header sig): 35508700841

it seems that unzip is not ready for such a large file

i tried also 7z (the command line tools), but it didn't work either with no error.

George

@hamidi or the zip file is corrupt or incomplete!

hamidi

yes, or, but how can i make sure? at first step, i prefer to accept the integrity of the zip file. because during making it, he didn't get any error.

George

Use the shasum from the source if avalable or or zip -T existing.zip

hamidi

what is it? calculates shasum for a file, like md5 or something? how can it help?

George

2:18 PM

Did you run zip -T name_of_zip_file.zip?

hamidi

no, but it will certainly be erroneous. the same thing is happening in unzip. if there's no support for such a large file from unzip, there'll be no support from zip too.

hi

hi

are we there?

i'm here

2:21 PM

ok zip and unzip are the same

they just do the opposite of each other's work

hamidi

sure

George

please run zip -T file_name.zip

hamidi

ok

zip warning: unexpected signature on disk 0 at 1145498486

zip warning: archive not in correct format: Files_downloaded_by_AirDroid.zip
zip warning: (try -F to attempt recovery)

zip error: Zip file structure invalid (Files_downloaded_by_AirDroid.zip)

George

it might take some time due to file size

there u go

it's not a complete zip file

hamidi

i thought so, but it didn't take any time. it prompted the response.

can i rely on the zip -T output?

George

2:24 PM

yes you can

hamidi

ok, so let's go into the source of the problem

George

it reads the file header so it would be fast

you have to re-download that file

hamidi

i've a folder in my android device

George

and pray your internet won't mess up

hamidi

by airdroid i send it to ubuntu as a zip file. this is how the file is created.

no it's not downloaded from the internet

George

2:26 PM

your android can handle flle of that size

hamidi

airdroid made it

George

what's in there

hamidi

about say 10000 files

George

files of what why do you need it to be in ubuntu?

hamidi

i can't copy the content to the PC by cable. because file manager of ubuntu times out while reading the content. so i decided to try airdroid

i need it to be moved into ubuntu because my cell phone has no room

George

2:28 PM

ok

then

ensure your connection to ubuntu is secure and good so you can move it

use a cable not blue tooth

hamidi

the ubuntu detects the connection and mounts the device

i'm using a cable

George

ok

then repeat it

hamidi

i also have wifi adapter attached to my pc

George

as it seems not to have moved the file

hamidi

i tried the cable several times with no success

George

2:31 PM

what type of files are these

hamidi

i can't move via cable. everytime it times out because of large number of files.

mostly images. lots of tiny images

reading the content takes time for ubuntu

George

how are you moving them from the command line

hamidi

oh not moving from command line

by file explorer

George

what is the size of your free space on ubuntu

hamidi

enough

308 GB

George

2:32 PM

ok

hamidi

it event doesn't have opportunity to begin moving

George

are u connect now?

hamidi

timeout occurs before moving (during calculation and analysis)

yes

George

ok

open the terminal

hamidi

ok, then?

George

2:34 PM

cd /media/$USER

hamidi

it doesn't mount there

George

where is it

hamidi

otherwise i could move it with no problem

let me examine

mtp://[usb:003,007]/

George

let me connect my phone

one moment

hamidi

cable connection to android devices is usually not reliable, especially when # of files is not less

George

2:37 PM

ok trying to find mine

hamidi

you may require to tap on 'allow' on the device

George

ok

connect ure phone then select media device

it's here /run/user/1000/gvfs/mtp:host=%5Busb%3A002%2C006%5D

are we ok

please hold on

ok

ok. i did

2:42 PM

ure file explorer shiuld open up

run

cd /run/user/1000

are good

hamidi

yes, but during move, it tries to calculate the content size and timeout occurs during this calculation.

George

one step at a time please

are we in /run/user/1000

hamidi

yes

George

run

ls

are we good

here is the content of mine

are we there

hamidi

i'm trying. just wait

George

2:47 PM

trying what?

hamidi

indeed ubuntu is trying to show the content

now i'm seeing the content

inside the content is the folder i'm going to move

it's named Telegram.2

George

that doesn't look like a zip file

i was expecting Telegram.zip

hamidi

oh a misunderstanding happened. airdroid maked the zip file 'on the fly' from contents of this folder. there's no zip file in the device.

the zip file is save on ubuntu

George

then do cp -R Telegram.s ~/

hamidi

ok let me examine

ok, i did this:
mv /var/run/user/1000/gvfs/mtp\:host\=%5Busb%3A003%2C015%5D/Phone/Telegram.2 .

my pwd was ~/t

then the command:
watch 'du -sh Telegram.2'
has remained at 8.0K

in another words, the content is not being moved

now i'm going to try cp...

oh i got:
mv: cannot access ‘/var/run/user/1000/gvfs/mtp:host=%5Busb%3A003%2C015%5D/Phone/Telegram.2/Telegram Images’: Input/output error

mv: listing attributes of ‘/var/run/user/1000/gvfs/mtp:host=%5Busb%3A003%2C015%5D/Phone/Telegram.2/Telegram Images’: No such file or directory

mv: cannot stat ‘/var/run/user/1000/gvfs/mtp:host=%5Busb%3A003%2C015%5D/Phone/Telegram.2/Telegram Audio’: No such file or directory

George

2:56 PM

please can e move with some order

your commands are off

hamidi

e move?

George

change into the Phone directory

hamidi

the cp command didn't help too

George

please try and follow my lead

hamidi

ok

now what i do?

George

2:57 PM

that's because you seem to have done it wrong

run

pwd

let me see that result

or go into the Phone directory

/home/hamidi/t

no

oh u mean i cd?

where is that phone mounted

I see /var mine was /run

hamidi

now i'm in /var/run/user/1000/gvfs/mtp:host=%5Busb%3A003%2C017%5D/Phone

George

3:00 PM

one moment

run

ls

and let me see tha result

now

run

cp -R Telegram.2 ~/

hamidi

ok

before everything i should thank you for your assistance. going to run

George

ok welcome

hamidi

it's running, but du -sh result indicates that nothing is copying. (remained at 12K)

cp: cannot access ‘Telegram.2/Telegram Images’: Input/output error

as i said before, cp and cable connection is not a reliable solution.

George

3:08 PM

are these files all images

hamidi

no

images, audio, video and documents

but it doesn't differ, it has stopped at the first step.

George

perhaps in place compression then move will help provided your phone has the memory to accommodate

how did you know it was 34GB

hamidi

iPhone connection to PC via cable is reliable and i've had no problem until now. but android really sux

George

well there's not much else I can suggest

hamidi

it was moved to PC by Airdroid. better to say it was made on PC

ok. thanks anyway

anyone else has any other suggestions?

George

3:12 PM

@DavidFoerster perhaps you have a suggestion?

hamidi

thanks for your time George in trying to solve the problem.

George

ok all the best then

David Foerster

3:39 PM

@George With what precisely? Extracting the Zip archive or copying files from the phone?

@hamidi: Does the Zip archive reside on a local drive or is it on the phone?

hamidi

it's on PC, as i said before

anyway, i just posted the solution.

thx

David Foerster

It would really help my understanding and that of future readers with similar issues if you edit your question to explain what exactly you did, what you tried to achieve and what happened instead including all error messages.
