This article describes how to find files in BCWipe Search using their names, locations, sizes, dates, file types, or similarities to other files.

You can combine multiple filters to narrow your search and find the files you need.


To search for information contained inside files, see Search Filters by Type of Information.



File Path (File Name)

This filter is used to search for files by specifying the full or partial file name or file path. The wildcard character * is supported. 

Matching is not case sensitive, so “file.txt” and “File.txt” are treated as the same.

Examples:


Expression

Result

C:\Data\*

All files in “Data,” including subfolders

C:\Data\*.txt

All .txt files in “Data” and subfolders

C:\Data\*.*

All files with any extension in “Data”

C:\Data*

All files in any folder in the root directory whose name starts with “Data”

C:\*\filename.doc

filename.doc located in any subfolder of the C: drive

*\filename.doc

filename.doc located anywhere on the computer



Size

The Size filter allows you to search for files based on their size. You can specify the size using kilobytes (KB), megabytes (MB), or gigabytes (GB), for example: “20 MB.”


To define a size range, create two filters and combine them using the AND operator. For example, to locate files between 5 MB and 10 MB, configure the following filters:


• Size: More than 5 MB

• Size: Less than 10 MB



When these filters are applied together, only files within the selected size range will appear in the search results.



Date Range

The Date Range filter allows you to search for files based on time-related attributes. You can choose one of the following file dates:


• Date created

• Date last accessed

• Date last modified


After selecting the appropriate date attribute, you can specify whether the filter should return files before or after the selected date.


To search within a specific period (for example, files modified in the last 30 days), create two filters and combine them using the AND operator:


• Date last modified: After 01/01/2024

• Date last modified: Before 01/31/2024


Only files that fall within that time window will appear in the search results.




File Type

The File Type filter allows you to search for files based on their extension. For example:


• PDF documents: .pdf

• Microsoft Word documents: .doc, .docx

• Text files: .txt


Search includes a predefined list of supported file extensions. When you add the File Type filter, several common file types are pre-selected automatically to help you start searching right away.

To refine the selection, open the dropdown list in the filter control and:

• Clear checkboxes to exclude file types you do not want to include

• Select additional checkboxes to include file types that are not pre-selected


This allows you to precisely define which file types should be included in the search.


If the required extension is not present in the list, you can add it manually in the configuration file (application.properties), under jcm.ai.file.type.list. Available in the upcoming update.



File Hash

The File Hash filter allows you to find files whose contents exactly match a selected reference file. This match is based on the file’s cryptographic hash value, so Search can identify identical files even if they have been renamed or stored in different folders.


To configure this filter, click Upload and select the reference file whose hash should be used for comparison.



This filter is useful for:


• Detecting unauthorized copies of sensitive files

• Finding duplicates stored across different locations

• Verifying file integrity across endpoints


Only files that exactly match the reference file’s hash are included in the search results.


Sample file

NOTE: The Sample file filter will be available in the upcoming Beta update.


The Sample File filter allows you to search for files with similar content to a selected reference file. This filter does not require an exact match. Instead, Search analyzes the textual content of files and compares it with the reference sample.

To configure the filter, click Upload and select a reference file.

The reference file size must not exceed 100 MB.



Search supports similarity analysis for the following file types:


.doc, .docx, .txt, .xls, .xlsx, .ppt, .pptx, .pdf, .odt, .ods, .odp, .epub, .fb2, .rtf, .html, .htm, .csv, .tsv, .xml, .zip, .chm


Search analyzes the first 500 words in each file and assigns a relevance score based on the number of matching words:


Match Level        Relevance Score

30+% match        Low

60+% match        Medium

90+% match        High


You can sort the search results by relevance to prioritize files that are most similar to the reference.


This filter is useful for identifying:


• Modified versions of a document

• Copies where only small changes have been made

• Files with shared topics, phrases, or content structure
