Requirement:
We need to take backup of project files/documents that are stored on a webserver in an content structure. This content structure have several catalogs, subcatalogs and files.

The file: Oppsummering KickOff Coop Bid 130103.ppt

The url:
pportal1.nextra.no\portal\binary\com.epicentric.contentmanagement.servlet.ContentDeliveryServlet\Focusweb\Bid\COOP\Dokumenter\Interne_252520m_2525C3_2525B8tereferat\Oppsummering_252520KickOff_25252016AE304

Our problem are now that we must first translate all of the "_2525.." and then rename all the files to the correct name. How can we solve this (It`s not a solutions to change the url at this time)

Thanks

Would it be possible to have a filter that replace some of the URL
like "com.epicentric.contentmanagement.servlet.ContentDeliveryServlet\" is replaced
with "servlet"... ?

Dear Thomas Fasteng,

Something is wrong here. Can you please tell me how some original URLs to the ppt files look like?

Regarding the replacement - do you want to replace some part of a URL with something else while downloading, so another URL will be downloaded in fact, not the one listed in the HTML file?

Best regards,

This is the full URL
"http://pportal1.nextra.no/portal/binary/com.epicentric.contentmanagement.servlet.ContentDeliveryServlet/Focusweb/Bid/COOP/Dokumenter/Interne%2520m%25C3%25B8tereferat/Oppsummering%2520KickOff%2520Coop%2520Bid%2520130103.ppt "

This is a Epicentric Foundation Server 4.1 SP1 solution. The epicentric framwork is an J2EE framework with servlets and this is what the user gets.

OK. As you probably know, % symbol is not allowed for file and directory names. That`s why Offline Explorer replaces it with _25. Next, since the URL is very long, Offline Explorer has to truncate the filename end and replace it with a unique signature to make sure the filename with the full file path (C:\....) are less than 256 symbols. This is why it happens.

Todays solution puts a signature at the end of the path (the file name). Is it possible to move the signature from the last part ot the path ?

But without that, there is a high chance that some filenames will be longer than the maximum allowed filenames length limit.

If you want, I can write a program that will try to revert such filenames to original names.

Yes please

For me it`s important to have the filename and if possible, directory path 1-5 levels up


Then it could be:
Focusweb\Bid\COOP\Dokumenter\Interne_motereferat\Oppsummering\KickOff Coop Bid 130103.ppt

or
\Dokumenter\Interne_motereferat\Oppsummering\KickOff Coop BID 130103.ppt

If the program copy this structure to a new structre it would be great

Like: Copy from <path> to <path>
with subdirectories

Another soulution could be the export possebility.

If I could choose the path/directory with (or without subdir) in the Map structre of the project and export this with correct filename endings.

Like:

Focusweb
Bid
Coop
Dokumenter
Eksterne_252520korrespondanse (DIR)
Adresselister fra Coop 00358057 (FILES)
VS Oversikt over ISDN_201D7EAF7 (FILES)

would be exported to:
Focusweb\bid\coop\Dokumenter Adresselister fra Coop (Intern).msg.msg
VS Oversikt over ISDN til butikker i Danmark.msg.msg

This is the correct filename (why .msg.msg is because user has saved the files as .msg.msg)

Does this help ?

Yes, I will look at how it could be done in the Export. Probably it will be really easier to do. I hope to come with some solution tomorrow.

Hi
When do you think that you will have a solution?

Sorry that it takes much time. The problem is not simple to solve. I made a partial solution so far. Now if you export a Project, it will replace all _252520 symbols with spaces and it will append .ppt extensions when necessary. However I cannot replace the unique file signature with the original filename, because in most cases the resulting filename will be too long and it will not simply fit filesystem limits. As a result you will get a filesystem error in the directory with exported files.

Here is the updated version:

http://www.metaproducts.com/download/betas/oep1141.zip

Please unzip it and replace the old oe.exe file with the new one.

OK - I see that.
Is it possible to make an export with the following functions
1. In the export meny: Translate this: "org path" with "new path"
The org path would be: "com.epicentric.contentmanagement.servlet.ContentDeliveryServlet"
The new path would be: "content"

(It would also be nice if you could have several translatation if neccesary)

2. Keep orginal file names if possible or a check like the Sigma for filenames that could not be kept in full.

Then it would be possible to browse the exported site with shorter url/path and have the correct file name with extension.

And then it would be simple for us to copy the files without manually renaming them (i big job)...
