Uploading and Managing Files

Uploading a file to dStorage

./zbox upload command is used to upload a file on dStorage. Parameters for uploading a file to dStorage can be viewed by using the ./zbox upload --help command.
Here are the Parameters :
Parameter
Required
Description
Default
Valid values
allocation
yes
allocation id, sender must be allocation owner
string
commit
no
save metadata to blockchain
false
boolean
encrypt
no
encrypt file before upload
false
boolean
localpath
yes
local path of the file to upload
file path
remotepath
yes
remote path to upload file to, use to access file later
string
thumbnailpath
no
local path of thumbnail
file path
Example :
Let's upload an info.txt file to allocation, the local path for the file is mapped to a local variable and the remote directory is mapped to a remote variable which is myfiles/info.txt.
Sample Command:
./zbox upload --localpath $local --remotepath $remote --allocation $ALLOC
Response:
Verify whether the uploaded file is available on dStorage using list command required parameters are allocation ID and remote path
./zbox list --remotepath $remote --allocation $ALLOC
Response:
TYPE | NAME | PATH | SIZE | NUM BLOCKS |LOOKUP HASH |
IS ENCRYPTED | DOWNLOADS PAYER
+------+----------+-------------------+------+------------+-----------------------------------------------
f | info.txt | /myfiles/info.txt | 24 | 4 | f15383a1130bd2fae1e52a7a15c4322
69eeb7def555f1f8b9b9a28bd9611362c | NO | owner
The response yields a lookuphash which works as a unique identifier for the uploaded file. Since you uploaded the file, the download payer section will show it as owner.
Copy and mark your lookup hash to a variable as it will be used for performing other file operations export LOOKUPHASH=f15383a1130bd2fae1e52a7a15c432269eeb7def555f1f8b9b9a28bd9611362c

Uploading an Encrypted File to dStorage

Parameters for encrypting and uploading a file to dStorage are almost the same as uploading a file on dStorage and only requires an additional --encrypt flag with the command.
For instance if we want to encrypt and upload a sample info.txt file the command would be:
Command:
./zbox upload --encrypt --localpath $local --remotepath $remote --allocation $ALLOC
Response:
24 / 24 [================================================================] 100.00% 0s
Status completed callback. Type = application/octet-stream. Name = info.txt
To verify whether the file is encrypted and uploaded to dstorage use the list command :
./zbox list --allocation $ALLOC --remotepath $remote
Response:
TYPE | NAME | PATH | SIZE | NUM BLOCKS |LOOKUP HASH
| IS ENCRYPTED | DOWNLOADS PAYER
+------+----------+-------------------+------+------------+-----------------------------------------------
f | info.txt | /myfiles/info.txt | 24 | 4 | f15383a1130bd2fae1e52a7a15c432269
eeb7def555f1f8b9b9a28bd9611362c | YES | owner
Scroll right in the response and check the IS ENCRYPTED section, it will say YES if the file is encrypted.

Updating the contents of a file on dStorage

Use ./zbox update command to update the content of an existing file in the remote path. Like upload command. Only the owner of the allocation or a collaborator can update a file. To add collaborators to an allocation, check File Collaboration.
Parameters for updating the contents of the file on dStorage can be seen by typing ./zbox update --help
Here are the parameters:
Parameter
Required
Description
Default

string
thumbnailpath
no
local fumbnail file to upload
file path
commit
no
save meta data to blockchain
false
boolean
Sample Command:
./zbox update --localpath $local --remotepath $remote --allocation $ALLOC
Verify the contents of updated file on dStorage using the list command.
./zbox list --remotepath $remote --allocation $ALLOC
Sample Response:
TYPE | NAME | PATH | SIZE | NUM BLOCKS | LOOKUP HASH
| IS ENCRYPTED | DOWNLOADS PAYER
f | info.txt | /myfiles/info.txt | 76 | 4 | f15383a1130bd2fae1e52a7a15c432

Note: To verify whether directory is created successfully run List all files command.

Sharing a File on dStorage

Zbox supports sharing of files using auth tokens. Sharing can be encrypted or not encrypted for this section we will describe the non-encrypted share functionality. For encrypted shared functionality have a look at Private Sharing .
./zbox share command is used to generate an authtoken that provides authorization to the holder to the specified file on the remotepath. Parameters for sharing the file can be viewed using the ./zbox share --help
The parameters are:
Parameter
Required
Description
Valid values
allocation
yes
allocation id
string
clientid
no
id of user to share file with, leave blank for public share
string
encryptionpublickey

string
expiration-seconds
no

int
remotepath
yes
remote path of file to share
string
revoke
no

flag
Command:
./zbox share --remotepath $remote --allocation $ALLOC
The response will yield an Auth token which can be shared publicly to users for downloading the file.
Sample Response:
Note: Use an export command and mark your Auth token to a variable to use with more commands
export AUTH= eyJjbGllbnRfaWQiOiIiLCJvd25lcl9pZCI6IjE3NTNkMjlkODE5ODkyNmZhYzJlZDQzYWNj

Downloading the file from dStorage

The ./zbox download can be used to download the file in two ways from dStorage. Using the Allocation ID or Authticket.

Download using Allocation ID and Remotepath

Parameters for downloading the contents of file from dStorage can be viewed using the./zbox download --help
Here are the parameters:
Parameter
Required
Description
Default
Valid values
allocation
yes
allocation id
string
authticket
no
auth ticked if not owner of the allocation, use share to get auth ticket
string
blockspermarker
no
download multiple blocks per marker
10
int
commit
no
save metadata to blockchain
false
boolean
endblock
no
download until specified block number
int
localpath
yes
local path to which to download the file to
file path
remotepath
yes
remote path to which the file was uploaded
string
rx_pay
no
authticket must be valid, true = sender pays, false = allocation owner pays
false
boolean
startblock
no
start download from specified block
int
thumbail
no
only download the thumbnail
false
boolean
Command:
./zbox download --localpath $local --remotepath $remote --allocation $ALLOC
Sample Response:
If you are not able to download files and getting Error in file operation: File content didn't match with uploaded file response check Error 2 in Tips and Troubleshooting Section.

Download using Authticket

The necessary flags for downloading the file using the Authticket is auth ticket and local path. Get the AuthToken for the file on dstorage from another user and mark it to a variable. We will use auth token created and marked to AUTH variable for the file we shared in sharing a file on dStorage section .
Command:
./zbox download --authticket $AUTH --localpath $local
Response:
28 / 28 [==========================================================] 100.00% 0s
Status completed callback. Type = application/octet-stream. Name = info.txt
As you can see Zbox has identified the file(info.txt) based on the auth token and didn't require any remote path and allocation id.

Deleting a File from dStorage

Deleting the file on dStorage can be done using the ./zbox delete command. Parameters for deleting the contents of the file on dStorage can be seen by typing ./zbox delete --help
Here are the parameters:

Verify whether the updated txt file is available on dstorage using the list command
./zbox list --remotepath $remote --allocation $ALLOC
Response:
TYPE | NAME | PATH | SIZE | NUM BLOCKS | LOOKUP HASH | IS ENCRYPTED | DOWNLOADS PAYER
+------+------+------+------+------------+-------------+--------------+-----------------+
As you can see the file is not showing in remote directory which means the file has been successfully deleted.

Copy File to Another Existing Folder in dStorage
