Check for Duplicate files.

I have multiple folders with duplicate files, i was wondering what is the best way to check for duplication based on file content even if the file name is slightly different.

There are several commercial software options. I suggest that you use the ones that use SHA1 matching.
Decloner is pretty good, and it comes with a 30-day trial that is FULL FEATURED.

Only works on snow leopard and up.
Their website conviniently compares other duplicate file software packages.
I purchased Twins, which is also great.

Remember, SHA1 is the way to go if you want to find duplicates with highest accuracy.

Need script to check for duplicate file names when copying a folder

Hello,
I am a new applescript user trying to write what I believe should be a simple script. I was planning on using the "add-new item alert" script as a template.
Basically I have people copying folders of photos into a library folder, but I don't want the Finder to copy the photo if it already exists in the library. The images in the library are organized into subfolders.
I need a script that will check all the file names in the new folder against all the file names in the library, and NOT add the new one if it already exists.
If anyone can help it would be greatly appreciated,
Thanks,
C

I have a script that "kind of" works. The only problem I've seen is that it gets confused when filenames contain characters that are fine in Macland but not good in Unixland. Forward slashes are a good example of this.
In this case I have a folder in my home named "copytest" Inside copytest are two folders:
Source (containing the images to be added)
Dest (My existing library of images)
It also assumes that the folder of images to be added contains no sub-folders. Hope this helps.
tell application "Finder"
set theSource to folder "source" of folder "copytest" of home
set imagesToBeCopied to name of every file of theSource
end tell
repeat with theFile in imagesToBeCopied
try
if (do shell script "find -r ~/copytest/dest -name " & quoted form of (theFile as string)) is not equal to "" then
--The file exists. Don't copy it
else
--the file doesn't already exist. Copy it.
end if
on error
return "Failed while trying to check for existence of a file"
end try
end repeat

Optimizing a search for duplicate files in a filesystem

We have a large directory that people have been dumping to for years (~200k files), and I want to go through and look for duplicate files. The first part of this was just scanning through and checking for duplicate file names. I wrote a simple VI to serarch for duplicates, but it is very inefficiant because of multiple string comparisons. Even optimized as much as I could think to do, I'm only scanning about 1k files / minute. I have attached my code - any help would be appreciated.

This is trivial using the variant attributes mentioned earlier. Attached is my method which uses the Variant Repository XNode I developed. Not sure on performance comparisions.
EDIT: I'm betting the thing that will take the longest will be performing the MD5, I'm sure a CRC32 could be done faster which is probably just as good in this situation, or even a sum of the bytes of the file as a quick way of identifying the file.

Check for duplicate record in SQL database before doing INSERT

Hey guys,
This is part powershell app doing a SQL insert. BUt my question really relates to the SQL insert. I need to do a check of the database PRIOR to doing the insert to check for duplicate records and if it exists then that record needs
to be overwritten. I'm not sure how to accomplish this task. My back end is a SQL 2000 Server. I'm piping the data into my insert statement from a powershell FileSystemWatcher app. In my scenario here if the file dumped into a directory starts with I it gets
written to a SQL database otherwise it gets written to an Access Table. I know silly, but thats the environment im in. haha.
Any help is appreciated.
Thanks in Advance

Hi
Since SQL Server 2000 has been out of support, I recommend you to upgrade the SQL Server 2000 to a higher version, such as SQL Server 2005 or SQL Server 2008.
According to your description, you can try the following methods to check duplicate record in SQL Server.
1. You can use
RAISERROR to check the duplicate record, if exists then RAISERROR unless insert accordingly, code block is given below:
IF EXISTS (SELECT 1 FROM TableName AS t
WHERE t.Column1 = @ Column1
AND t.Column2 = @ Column2)
BEGIN
RAISERROR(‘Duplicate records’,18,1)
END
ELSE
BEGIN
INSERT INTO TableName (Column1, Column2, Column3)
SELECT @ Column1, @ Column2, @ Column3
END
2. Also you can create UNIQUE INDEX or UNIQUE CONSTRAINT on the column of a table, when you try to INSERT a value that conflicts with the INDEX/CONSTRAINT, an exception will be thrown.
Add the unique index:
CREATE UNIQUE INDEX Unique_Index_name ON TableName(ColumnName)
Add the unique constraint:
ALTER TABLE TableName
ADD CONSTRAINT Unique_Contraint_Name
UNIQUE (ColumnName)
Thanks

How to check for duplicates - with a twist?

As I'm importing music from my CD collection, is there a way to automatically check for duplicates - with an unusual twist?
I already imported about 70 CDs using AAC format.
I just bought a huge external drive specifically for storing my entire collection of CDs and LPs. Now that I have lots of space, I want to import everything in Apple Lossless format.
Is there an automatic (or at least painless) way to check for duplicates as I'm importing CDs, and to have the old AAC music files over written by the new Apple Lossless files?

Hi Clinto,
Do you see the column headers above in itunes? They say Title, Album, Artist, etc. I don't know if it's the same for MAC but in Windows, Right Click on the column headers and click "Kind". This will display the format each song is in. If your column headers already take up all of your screen, you're gonna have to uncheck one to make room for "kind".
Oh! and to overwrite existing files, make sure the ID3 tags are filled exactly to the old ones prior to ripping, though you don't need to fill all of them. I think you just fill the Artist, Album Artist, Album, and Title. A window will appear as you start to rip. It will ask if you want to overwrite the existing files, click "Yes". Again, don't know about Mac but it works this way in Windows.

Can't get Firefox to load at all after trying fixes from support web site. Have checked for lock file, processes running, reboot, reinstall. NO JOY.

I'm running Vista for operating system on an HP laptop that's about 2 years old. I've installed all current updates.
I've always used Firefox. It started crashing and creating processes but not launching. Went to support and scoped it out -- there was a lock file my profile directory. I deleted it, and Firefox started loading.
Used it a few times -- closed the app each time on exist as per suggestions on support site info. One time -- back to square one, wouldn't load, just created a process. Reboot, ending process, checking for lock file, reinstalling -- all unsucessful.

Below is from using a SIP build. It does offer G722, but it's way down on the list so it's never used...
m=audio 32678 RTP/AVP 0 8 18 102 9 116 101
a=rtpmap:0 PCMU/8000
a=rtpmap:8 PCMA/8000
a=rtpmap:18 G729/8000
a=fmtp:18 annexb=no
a=rtpmap:102 L16/16000
a=rtpmap:9 G722/8000
a=rtpmap:116 iLBC/8000
a=fmtp:116 mode=20
a=rtpmap:101 telephone-event/8000
Taking Sreekanth's suggestion to try a Skinny build, I get the following when I make a call. It offers codecs in the order I SET THEM AND ONLY THE CODECS I SET! YAY!
m=audio 19374 RTP/AVP 9 0 101
a=rtpmap:9 G722/8000
a=fmtp:9 bitrate=64
a=rtpmap:0 PCMU/8000
a=rtpmap:101 telephone-event/8000
Using a Skinny build on the phones also solved other issues. The phones use G711 when the whole path supports G711 and G722 when the whole path supports G722. It doesn't always use G722 and rely on transcoding for the call paths that can't use it. It's fantastic.. The phones also receive the QoS tagging that I set and that seems to result in better audio quality than on the SIP builds, which never did get those settings. Finally, it even solved a slow Exchange 2013 answer issue I have been experiencing for quite some time. I practically fell out of my chair when I saw everything that was fixed just by switching...
Cisco, PLEASE FIX YOUR SIP BUILDS! It's insane how the SCCP builds work perfectly and the SIP builds don't, especially with how much these phones cost.. I was thinking of possibly acquiring some 9951s, which are SIP only. I'm a little leery about that at this point. If they have the same kinds of issues as the SIP builds for the 7975g, there's no SCCP alternative to use..
Sreekanth
Thank you for suggesting a Skinny build.. That was about the only thing I didn't try. I am happy beyond belief that this is working so well now, even though the SIP builds should be just as well developed as the SCCP ones.

How do i check ensure that SAP checks for duplicate vendor invoice numbers?

Hi Experts -
How do I verify that SAP checks for duplicate vendor invoice numbers and blocks duplicate invoices from being paid?
Thanks!

Hi
Pls chek the settigs by following the path
IMG>Materials Management>Logistics Invoice Verification>Incoming Invoice>Set Check for Duplicate Invoice.
Here you make the settings for creating a duplicate invoice check.
Moreever, in the vendor master, you need to tick the check box for duplicate invoice check.
I suggest you search the Forums before posting a query. There are lots of postings on this issue.
Thanks & regards

Problem in Set Check for Duplicate Invoices
Edited by: UJ on May 15, 2009 1:45 PM

Hello,
Hope you have done all the required configurations for the checking of double invoice and ticked the vendor for the double invoice checking in vendor master record.
You have to understand the way the system does the double invoice check.
As per the configuration, if the system identifies an invoice for a vendor whose double invoice check is activated, at the time of MIRO, system will update a separate table.
So system will check for the double invoice entry among the invoices entered after making the tick in the vendor master.
i meant to say that, if you are introducing this double invoice check in between the transactions, the check will be valid only for the invoices entered after the activation of double invoice check.
Regards

Set Check for Duplicate Invoices.

Hi,
what is the difference if is set "<b>Set Check for Duplicate Invoices</b>"
in MIRO?
Best regards

HI,
This check will prevent incoming invoices being accidentally entered and paid more than once.
You can choose whether to activate or deactivate the check criteria of company code, reference document number and invoice date for each company code. The more criteria that you activate, the lower the probability of the system finding a duplicate invoice.
The company code check makes sense if you work with more than one company code.
Depending on the reference document number entry, the system checks as follows:
1. If you have entered a reference document number, the system checks whether the invoice matches in the following attributes:
Company code
Vendor
Currency
Invoice date
Reference document number
2. If you have not entered a reference document number, the system
3. checks whether the invoice matches in the following attributes:
Company code
Vendor
Currency
Invoice date
Amount in
document currency
Depending on the system settings, a warning message or an error message appears if the system finds an invoice that matches all attributes.
Requirements
The field Chk double inv. (Check for duplicate invoice) must be flagged on the Accounting view in the vendor master record.
Regards
Aasif

Check for duplicate invoices and trigger a workflow

Hello All,
I have a requirement to check for duplicate invoices in AP(Accounts payable) and trigger a workflow when duplicate invoices are found. I a not sure how to do any of the above. Please let me know if you have any information on:
1) Checking for duplicate invoices in AP
2) Trigger a workflow
Are there any standard workflows that checks duplicate invoices?
Thanks.
--Mithun

Hi MD,
I doubt if system gives an error on FI side when a duplicate invoice is posted.
I feel you would require a BAdi for it, where you can call your WF using FM SAP_WAPI_START_WORKFLOW.
Hope it helps.
Aditya
P.S also ask your Func Consultants, if there are any settings in the Customization, where you could capture Inv Dt, Inv Amt, Vendor, Company code.

Maybe they will in a future update. Im not sure but I think they use to do this. IF they did Id say they stopped to make the record companys happy (And alittle richer)
