+    <H1>Source File Information</H1>
+
+    <P>Ghidra can store information about the source files for a program, including their locations
+    in the build environment and the correspondence between lines of source code and addresses in a
+    program. A common source of this information is debug data, such as DWARF or PDB.</P>
+
+    <P>A major use case of this information is to synchronize Ghidra with an IDE, such as
+    Eclipse.</P>
+
+    <H2>Source Files</H2>
+
+    <P>A source file record in Ghidra consists of three pieces of information:</P>
+
+    <BLOCKQUOTE>
+      <OL>
+        <LI>A path, which must be an absolute, normalized path using forward slashes (think file
+        URI).</LI>
+
+        <LI>A <I>SourceFileIdType</I>, which can be NONE, UNKNOWN, TIMESTAMP_64, MD5, SHA1, SHA256,
+        or SHA512.</LI>
+
+        <LI>An identifier, which is the value of the identifier as a byte array.</LI>
+      </OL>
+    </BLOCKQUOTE>
+
+    <H2>Source Map Entries</H2>
+
+    <P>A <I>Source Map Entry</I> associates a source file and a line number to an address or
+    address range in a program. It consists of:</P>
+
+    <BLOCKQUOTE>
+      <OL>
+        <LI>A source file.</LI>
+
+        <LI>A line number.</LI>
+
+        <LI>A base address.</LI>
+
+        <LI>A length. If the length is non-zero, the entry defines an address range, otherwise it
+        defines an address.</LI>
+      </OL>
+    </BLOCKQUOTE><BR>
+     <BR>
+     
+
+    <P>Source map entries are constrained as follows:</P>
+
+    <BLOCKQUOTE>
+      <UL>
+        <LI>An address in a program may not have duplicate (same source file, line number, base
+        address, and length) source file entries.</LI>
+
+        <LI>Given two source map entries with non-zero lengths, their associated address ranges
+        must be either identical or distinct (i.e., no partial overlaps). Multiple source maps
+        entries based at the same address are allowed as long as they obey this restriction. Length
+        zero entries may occur anywhere, including within ranges corresponding to entries of
+        non-zero lengths.</LI>
+      </UL>
+    </BLOCKQUOTE><BR>
+     <BR>
+     
+
+    <H2>Source File Manager</H2>
+
+    <P>Source files and source map entries are managed by a program's source file manager (accessed
+    via Program.getSourceFileManager()). A source file must be added to a program before it can
+    used in a source map entry.</P>
+
+    <BLOCKQUOTE>
+      <P><IMG src="help/shared/note.png" alt="Note" border="0">Note that adding source files,
+      removing source files, or changing the source map requires exclusive access to a program.
+      Reading the source file list or source map does not require exclusive access.</P>
+      <BR>
+    </BLOCKQUOTE><BR>
+     <BR>
+     
+
+    <H2>Source Path Transformations</H2>
+
+    <P>Source file path information can be sent to an external tool, such as an IDE. However, there
+    is no guarantee that a path recorded for a source file exists on the machine running Ghidra.
+    For instance, you could use Ghidra running under Linux to analyze a Windows program with source
+    file information. An additional complication is that the program may be in a shared Ghidra
+    repository where users have different operating systems or local file systems. We solve this
+    issue by allowing users to modify source file paths. The modifications are stored locally for
+    each user and are not checked in to a shared repository.</P>
+
+    <P>A note on terminology: to avoid overuse of the word "map", we use "map" when discussing the
+    association of a source file and a line number to an address and length in a program (the
+    "source file map"). We use the word "transform" when discussing user-determined modifications
+    of a source file's path.</P>
+
+    <P>There are two type of source path transforms:</P>
+
+    <BLOCKQUOTE>
+      <OL>
+        <LI><I>File Transforms</I>, which entirely replace a source file's path with another file
+        path.</LI>
+
+        <LI><I>Directory Transforms</I>, which replace a parent directory of a source file's path
+        with another directory.</LI>
+      </OL>
+    </BLOCKQUOTE><BR>
+     <BR>
+     
+
+    <P>Given a source file, the transformed path is determined as follows. If there is a file
+    transform for that particular file, the file transform is applied. Otherwise, the most specific
+    directory transform (i.e., the one replacing the longest initial segment of the path) is
+    applied. If no transform is applied, the user may opt to use the untransformed path.</P>
+
+    <P>Source file path transformations are managed using a <I>SourcePathTransformer</I>. Path
+    transformations can be managed using the actions on the <A href="#Source_Files_Table">Source
+    Files Table</A>. In a script, you can get the path transformer for a program via the static
+    method <I>UserDataPathTransformer.getPathTransformer(Program)</I>. Note that modifications to
+    the path transformer are not affected by undo or redo actions in Ghidra.</P>
+
+    <H1><A name="Source_Files_Table_Plugin"></A>Source Files Table Plugin</H1>
+
+    <P>This plugin shows the source file information associated with the current program and allows
+    the user to manage source file path transforms.</P>
+
+    <H2><A name="Source_Files_Table"></A>Source Files Table</H2>
+
+    <BLOCKQUOTE>
+      <P>Each row in this table corresponds to a Source File added to the program's source file
+      manager. The columns show the source file, path, transformed path, and number of source map
+      entries for a source file. If the <I>Transformed Path</I> column is empty for a given source
+      file, then no transformation applies to that file. Note that there are optional columns,
+      hidden by default, to show the SourceFileIdType and identifier of each source file.</P>
+
+      <H3><A name="Reload_Source_Files_Model"></A>Reload Model</H3>
+
+      <P>This action reloads the Source File Table. Note that this can be an expensive operation
+      since the number of source map entries must be computed for each source file. For this
+      reason, the action is only enabled after program events which might change the data shown in
+      the table.</P>
+
+      <H3><A name="Show_Source_Map_Entries"></A>Show Source Map Entries</H3>

+      selected source file.</P>

+
+      <P>This action allows you to create a file transform for the selected source file. The input

+
+      <H3><A name="Transform_Directory"></A>Transform Directory</H3>
+
+      <P>This action allows you to create a directory transform whose source is a user-selected
