I'm using TypeScript to write an upload utility. Basically, it's just a div listening for a drop event.
Uploading uncompressed files or zip files works fine, but when a user drags and drops a file from within a zip file to my upload area, the uploaded file is corrupted (i.e. not decompressed).
Is there a way to determine if the file to be uploaded resides in a zip file? It would be nice to perform a check in my drop event before executing the actual upload. I can't find anything in the dataTransfer object.

With struts, the uploaded files will be saved as tmp first, how to guarantee the uploaded files are in sequence, since I have to save them with the original file names?
How can I use the "Download File" component to only download new files or files that have been updated remotely?
Consider a graph like the following:
where File Download is defined as:
I have many *.csv files in ${S3_OR_DATA_DIR_LOCATION}; I'm adding one every day).
How can I make sure GoodData only downloads new files AND files that have been updated? Would making the option "Overwrite existing files" False do it? Or would that only download new files and not update existing files that have been updated?
The File Download CloudConnect component by itself does not support action as downloading only a new file(s), which appeared in the source folder as it does not have any previous state remembering mechanism implemented, but as it has input port, it is possible to implement such mechanism yourself with using of File List CloudConnect component with a little help of Reformat, some Joiner and CSV Writer CloudConnect components. This way you can determine the content of the source folder and write it there in a plain text file. The mechanism can be designed the way, that the next processing would read the state file from the previous run and determine, what a new files are and then sends a list of a new files to the File Download CloudConnect component’s input port.
The another way how to process only a new files, which is way simpler then the process described in the previous article and therefore commonly used, is based on taking advantage of folder structures in the source folder, where there would be a dedicated folder for a new files and another dedicated folder for already processed files. The CloudConnect ETL process itself would then read a new files from its dedicated source folder and the last stage of the ETL process would contain File Copy/Move CloudConnect component used for transferring of the already processed new files from its dedicated folder to folder containing all already processed files.
I am creating a Flowgear workflow that needs to process a raft of XML data.
I have the xml data contained in a set of .xml files (approximately 400 files) in a folder on my local machine hard-drive and I want to read them into a workflow, run an XSLT transform and then write out the resultant XML to another folder on the same local hard-drive.
How do I get the flowgear workflow to read these files?
It depends on the use case, the File Enumerator works exceptionally well to loop (as in for-each) through each file. Sometimes, one wants to get a list of files in a particular folder and check whether a file has been found or not. For this, I would recommend a c# script to get a list of files with code:
Directory.GetFiles(#"{FilePath}", "*.{extension}", SearchOption.TopDirectoryOnly);
Further on, use the File node to read, write, or delete files from a file directory.
NB! You will need to install a DropPoint on the PC/Server to allow access to the files. For more information regarding Drop Points, please click here
You can use a File Enumerator or File Watcher to read the files up. The difference is that a File Enumerator will enumerate all files in a folder once, the File Watcher will watch a folder indefinitely and provide new files to the workflow as they are copied into the folder.
You can then use the File node to write the files back the the file system.
I’m making a simple web browser for work eeh, what I’d like to know is if its possible to save a file of a particular extension to a particular file.
I currently use google chrome when downloading a file it places this (regardless of extension) in a downloads folder without asking where I ant to download this too.
I want to achieve the same except that downloads with the extension .dwg are placed automatically in a folder named DWG DOWNLOADS…
How to achieve this in vb.net?
In any browser you have a config section.
In Firefox you have browser.download.useDownloadDir;true and browser.download.folderList;1
you can add your own config to allow different saved folder paths and dynamically modify them depending on the extension of the file you uploaded.
See a complete list of the web browser config with about:config in address bar.
Not real sure what you are asking, but if you are actually making a web browser just check the extension of the file you are requesting to download. If the extension is ".dwg" then save the file to the folder you want.
If you are wanting to automatically move Google Chrome downloads to a different directory, you can use a FileSystemWatcher to monitor for new files in Chrome's download directory and move them to another folder based on each file's extension.
I am trying to setup a backup/restore using S3. The upload sync worked well using s3sync. However, next to each folder there is an empty file with matching name. I read somewhere that this is created to define the folder structure but I am not sure about that as it doesn't happen if I create a folder using a different method s3fox etc.
These empty files prevent me from restoring the directories/files. When I do s3cmd sync, I get an error message "can not make directory: File exists" as it first creates that empty file and that fails when trying to create the directory. Any ideas how I can solve this problem?
