Move data to Dropbox project folder based on filename information
Q: Move data to Dropbox project folder based on filename information
Objective: Move data from server to Dropbox project folder based on filename information.
Example of such a filename: P9876543210_122123_EI0001_BIA1234C.zip
The Project Number is the first part until the underscore > P9876543210 This Project Number should be available in one of the Dropbox subfolders, so you’ll need to scan the subfolders of the Dropbox as Destination Root folder. There may be cases where the Project Number cannot be found in the Dropbox. This could be due to a typo or incorrect formatting by the scientist when setting up the experiment. In this case the .zip should be moved to the Dropbox …\Clients\Unknown\ directory.
A: We added a new option in version v2024.1.20.0 to achieve this.
We used a Windows folder as Source. In this folder we’re going to search for the project zip files.
Added the following include filename filter because we are only interested in .zip files:
Next, please open our Pascal Script option:
Enable and Add the following ‘On Destination’ Pascal Script:
Please add the following script: link
This script will:
strip the project number from the filename into variable %VSA
P9876543210_122123_EI0001_BIA1234C.zip > P9876543210 > %VSA
remove the project number from the filename into variable %VSB
P9876543210_122123_EI0001_BIA1234C.zip > 122123_EI0001_BIA1234C.zip > %VSB
Both variables will be used in the Dropbox as Destination setup
We added our Dropbox as Destination option and adjusted the Directory option > ‘/Clients’:
Dropbox OAuth2 setup:
Enable ‘Send Code Challange’
Enable ‘Include Nonce’
Authorization Endpoint URL: https://www.dropbox.com/oauth2/authorize
Token Endpoint URL: https://api.dropboxapi.com/oauth2/token
Add your Client ID and Client Secret (= App Secret)
As scope we used:
files.metadata.read files.metadata.write files.content.read files.content.write
Type was set to:
code
Do not forget to set the Redirect URI (must be exact)
http://localhost:3017/
Click <GET> and follow the procedure. Afterwards Refresh and Access Token will be automatically added.
Now the important part. We added our new ‘Search for Subdir Options’ under the ‘File & Directory’ Tab. So in our setup we will be looking for a subdirectory through all existing subfolders of the Dropbox Destination Directory with the name ‘%VSA/Data’ which converts using our example filename to ‘P9876543210/Data’. The variable %VSA is determined by the previous Pascal Script. The reason we added the /Data part is because the customer requested to store the files within a Data subfolder of the corresponding Project directory.
If we don’t find this subdirectory then Clients/Unknown will be used. This ‘Search and replace Directory default full path’ must be a full path meaning starting from the home folder.
We also added file renaming because the customer wanted to strip the Project number from the original Source filename.
The complete filename will be replaces with the content of variable %VSB

How to access the dropbox root namespace
How to access the dropbox root namespace
Q: So we still aren’t able to see root access of the dropbox, i read through this and this looks like a coding issue but we really don’t know enough about it to be sure. I wanted to run it past you and get your thoughts. Let us know when you have some time so we can catch up.
A: In version v2023.12.31.0 we added a custom headers option fro Dropbox
A very interesting article can be found here
We are going to use the following header entry:
Dropbox-API-Path-Root: {“.tag”: “root”, “root”: “7”}
So add the following entry to both headers, ‘API Requests’ and ‘Content Request’:
If you don’t know your Root ID then just add a dummy like we did, we used 7 like in the article. Click connect and you’ll receive an error if the Root ID is not correct (invalid_root). Please copy the correct root_namespace_id from the RunTime log into the Header Value. Don’t forget to adjust both ‘API Requests’ and ‘Content Requests’ headers.
$limagito file mover access the dropbox root namespace\access the dropbox root namespace.01.png$
After the adjustment of the Root ID we are able to access all folders:
Some extra information about the ‘API Requests’ and ‘Content Request’ headers. We added the possibility to add different headers to the part that is doing the control requests (API Requests) and the part doing the file upload/download requests (Content Requests). This makes it possible for Dropbox specialists to tweak our DropBox option.

How to upload large files to Dropbox using Limagito File Mover
Uploading large files to Dropbox
The default Dropbox upload API endpoint allows us to upload files up to 150MB. In version v2023.7.31.0 we optimized our code to automatically switch to a another API endpoint which allows us to upload larger files. This is all done automatically.
When ‘Large File Mode’ is used (files > 150MB):
We will upload the file in blocks of 32MB
For each of these 32MB blocks, we will calculate and send the SHA-256 hash code
This hash code will be used by Dropbox to check if the received block is OK.
If something goes wrong during the upload of a block, we’ll retry this block up to 3 times
At the end we’ll receive the total hash of the uploaded file from Dropbox which we’ll compare to be 100% sure
