I tried to list the files in my local directory as well as to read a file. But was not able to do it. Can any one give me sample code to get the list of files in a directory using gwt-filesystem.
It depends from where you are reading. You can't obviously read from the client due to security issues (any HTML wouldn't let you do that). However, you could obviously read the list of files in a folder from the server side.

I have got a service running in a specific directory in 5-second-intervals which is picking up an XML file created in that directory sending it for some necessary authorization checks to another client and then requesting a response file.
My issue is that my Z_PROGRAM creating the XML file might take longer than 5 seconds as a result of the file's size. Therefore creating the file in that specific directory is not preferable. I thought about creating a new folder in that directory called "temporary" and creating the file inside that folder, then once I'm done with it, moving it back outside for the service to pick it up.
Is there any way to move files from one directory to another via ABAP code only?
Copying the file manually is not an option since the problem that I have during file creation still persists. I need 2 alternatives, one used for local directories and one for application server directories. Any ideas?
Generally, we create another empty file for completed files after the file creation process ends. Third parties must be firstly checked empty file is there. Example:
data file.csv
data file.ok
If you already completed your integration and it is not easy to make any change with third parties, I prefer using OS level file moving commands. Sample document here. You can use mv for Linux server and move for Windows. If your file is big, you will get same problem with OPEN DATASET concept. We have ARCHIVFILE_SERVER_TO_SERVER FM for moving files but it is also using OPEN DATASET.
there is no explicit move command in ABAP code that move or copy files between directories in application server.
there is two tips can be helpfull in your case. if you are writing big file you may seperate the logic behind collecting data and writing file. I would say don't execute transfer data inside your loop. instead collect you data into an internal table once you're done, loop over this internal table and write direclty strings without any delay you should be able to write a big files upp to several hundred of MB under 1 sec.
next tips is to not modify your program, or if you are using function modules to construct xml is, write to a temp directory after finishing, then have another program open you file on source directory by read dataset and directly write data to the new directory again just strings without interruptions.
you should be ok if you just write strings.
You can simply use System Call Commands to perform actions in Application Directory.
CALL 'SYSTEM'
ID 'COMMAND'
FIELD 'mv /usr/sap/temporary/File.xml
/usr/sap/final/file.xml'
I have a local markdown file containing several links and I want that links head to local file like pdf.
I use the following syntax:
[my link](file:///C:/my_file.pdf)
But when I open my markdown file into a Firefox page and click on the link, nothing happens.
What exactly have I missed? Is it possible to open local file?
None of the answers worked for me. But inspired in BarryPye's answer I found out it works when using relative paths!
# Contents from the '/media/user/README_1.md' markdown file:
Read more [here](./README_2.md) # It works!
Read more [here](file:///media/user/README_2.md) # Doesn't work
Read more [here](/media/user/README_2.md) # Doesn't work
How are you opening the rendered Markdown?
If you host it over HTTP, i.e. you access it via http:// or https://, most modern browsers will refuse to open local links, e.g. with file://. This is a security feature:
For security purposes, Mozilla applications block links to local files (and directories) from remote files. This includes linking to files on your hard drive, on mapped network drives, and accessible via Uniform Naming Convention (UNC) paths. This prevents a number of unpleasant possibilities, including:
Allowing sites to detect your operating system by checking default installation paths
Allowing sites to exploit system vulnerabilities (e.g., C:\con\con in Windows 95/98)
Allowing sites to detect browser preferences or read sensitive data
There are some workarounds listed on that page, but my recommendation is to avoid doing this if you can.
You link to a local file the same way you link to local images. Here is an example to link to file start_caQtDM_7id.sh in the same directory as the markdown source:
After messing around with #BringBackCommodore64 answer I figured it out
[link](file:///d:/absolute.md) # absolute filesystem path
[link](./relative1.md) # relative to opened file
[link](/relativeToProject.md) # relative to opened project
All of them tested in Visual Studio Code and working,
Note: The absolute and relative to opened project path work in editor but don't work in markdown preview mode!
If you have spaces in the filename, try these:
[file](./file%20with%20spaces.md)
[file](<./file with spaces.md>)
First one seems more reliable
This is a old question, but to me it still doesn't seem to have a complete answer to the OP's question. The chosen answer about security being the possible issue is actually often not the problem when using the Firefox 'Markdown Viewer' plug-in in my experience. Also, the OP seems to be using MS-Windows, so there is the added issue of specifying different drives.
So, here is a little more complete yet simple answer for the 'Markdown Viewer' plug-in on Windows (and other Markdown renderers I've seen): just enter the local path as you would normally, and if it is an absolute path make sure to start it with a slash. So:
[a relative link](../../some/dir/filename.md)
[Link to file in another dir on same drive](/another/dir/filename.md)
[Link to file in another dir on a different drive](/D:/dir/filename.md)
That last one was probably what the OP was looking for given their example.
Note this can also be used to display directories rather than files.
Though late, I hope this helps!
Thank you drifty0pine!
The first solution, it´s works!
[a relative link](../../some/dir/filename.md)
[Link to file in another dir on same drive](/another/dir/filename.md)
[Link to file in another dir on a different drive](/D:/dir/filename.md)
but I had need put more ../ until the folder where was my file, like this:
[FileToOpen](../../../../folderW/folderX/folderY/folderZ/FileToOpen.txt)
If the file is in the same directory as the one where the .md is, then just putting [Click here](MY-FILE.md) should work.
Otherwise, can create a path from the root directory of the project. So if the entire project/git-repo root directory is called 'my-app', and one wants to point to my-app/client/read-me.md, then try [My hyperlink](/client/read-me.md).
At least works from Chrome.
I'm trying to make a simple batch for windows that will basically sync two folders, the catch is that the files in the folders can be named arbitrarily and the snyc should be based on the checksum. I've only found information about xcopy that compares the timestamp so I'm wondering if this is possible in a simple matter at all.
Here is the scenario I'm trying to manage, you've got the "Import Folder" containing the files named A_2.bmp and A_3.bmp and the "Target Folder" containing file A_1.bmp.
File A_2.bmp is infact the same file as A_1.bmp, just with a different name and thus should be skipped, A_3.bmp should then be copied over to target folder and icrementally renamed to A_2.bmp.
This probably sounds more like a work for patching software, but I'm looking for a solution that doesn't require building patches all the time and is open for the user (so he can just drop files into the import folder and run it whenever the need arises)
If there is software for such a thing that is free and can be distributed without installing I would also consider this a good option, but I haven't found anything.
I'm thankful for any advice and help on this matter so thank you very much for your time and help!
You have this command line utility :

You can then make a bat who simply test the checksum of the files
I want to essentially make it so that you never need to unzip/unrar any files. Currently, I have a Dokan filesystem which can do it given a specific zip file but I wanted to know how I can make it apply to all files. Meaning, I want to be able to compile a program that has "fopen("test.zip/1.jpg", "rb");". I think that a Shell Extension would work for dynamically loading the file into the filesystem IF I were browsing in the shell explorer but that doesnt help me with the fopen example. Any ideas?
What you want to do can be used with help of file system filter driver, which would track directory enumeration requests and report directories in place of ZIP files. Then this driver would create virtual files and take the data from ZIP archives. Quite a lot of kernel-mode work, I should say. And file system filter driver is not a file system driver, so dokan won't help you at all.
from my slapd.conf file, i see where my data is stored. when I look into that data directory i see two kinds of files, one type are .bdb files which appear to be the data files as that is the extension defined in the config file. But, I also have a bunch of log files, which appear to be binary when I try to read them in vi. I'm not sure if they are supposed to be there or if this is an oversight by someone previous to me. If I want to restore from an .ldif file, am I loosing anything by deleting all the log files? do I just need to delete the bdb files?
They are Berkeley DB files.
On Ubuntu 10.04, for example, you can install the db4.7-util package and get some information using the various db4.7_* utils (e.g. db4.7_dump or db4.7_stat). This being said, the structure of the database really depends on how OpenLDAP is coded (it's an internal format, so it's not particularly useful unless you really want to dig into it).
If you want to restore from an LDIF file, use LDAP clients or OpenLDAP commands such as ldapadd.
