Exclude folder from scan

Each ResourceScanServiceHost exists under the label Service 3 attributes:


They are initially set as follows:

varusionsFolders = new HashSet <string> {"$ recycle.bin", ".snapshot", "system volume information"};

var excludedFiles = new HashSet <string> {".mig.raven", "thumbs.db", ".ds_store"};

The paths are initialized as spaces and the individual values ​​are separated with a semicolon.

These properties can be adjusted at any time in the database interface. Uppercase and lowercase letters can be ignored here because they are internally normalized against a lowercase spelling variant.

The 3 properties are used in the ResourceScan to filter out "unwanted" data. This also already affects the entry point.

Possible changes in the DB are available to the service when forming the proxy, ie directly at the next scan.

Write the entries first in lowercase. Paths with their "\" must be masked in Java and C # - in the DB, then \\\\ server \\ share \\ directory

Care must be taken with paths and folders as the recursion is aborted at this point. Wildcards are not supported at this point (attention performance).

HTTP Error 403.14

If the browser throws the 403.14 error message when the Web client is invoked, the cause is to look in the Windows features:

Enable HTTP activation under the WCF services and start under certain circumstances
the website in IIS new.

This should correct the error.

Adapt database heap size

Depending on the configuration of migRaven, it is recommended to adjust the heap size in the database config, otherwise there could be difficulties with the saving process in the database.

The installation sets a default value.

The recommended size is 50% of the available memory.
(64 GB RAM, 32 GB heap size)

Overlength pathnames on Windows 10 / Windows Server 2016

With Windows 10 exists since the Anniversary update (Version 1607) the theoretical possibility to cancel the limit for the standard 260 character limit.

In the registry can be found below HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Filesystem a DWORD (32-bit) named LongPathsEnabled.

Under a standard installation this is with the value 0 deposited. Change this to 1 to activate the option.

The same change can also be implemented with a GPO, with the same setting in the background.

The practical benefit

Unfortunately, this does not affect the entire system as expected.

Some applications may benefit from this setting (eg PowerShell). For other standard Windows programs, such as the "explorer.exe" or the "cmd.exe", this setting does not apply. Thus, this character limit can also within the use of migRaven not be bypassed.


The removal of this limit is always at your own risk.
Windows uses a #define constant named MAX_PATH to specify the size of character arrays to store path / file names.

Increasing this limit can result in a buffer overflow on a path that works like this
which can usually lead to a crash of the application.

Open controls according to left- or right-handed setting

On touch display computers, it can happen that an autocomplete box opens to a page and it is difficult or impossible to reach the content with the mouse. Alternatively, the box opens only briefly and then closes again immediately. The direction in which a box opens depends on the attitude of "handedness". There is a right- and a left-handed setting. Changing these can solve the mentioned problems.

Build up NTFS list permissions optimally

1. Need for list permissions

As a rule, access rights to NTFS file servers are not lower than 1. Assign directory level. As soon as this is the case, you have to make sure that the user can also browse through the file system to the appropriate directory. There are different possibilities with different effects.

2. Variants of the allocation of list rights
