CalmQuery <RowLimit> not working - sharepoint-online

Question

I try to get some files from a folder, inside a folder inside a list. To do this, I try to use a CalmQuery with a RowLimit because I have lot of files in this folder.
But when I execute the code, it appears that my row limit didn't work.
$list = $context.Web.Lists.GetByTitle($ListName)
$context.Load($list)
$query = New-Object Microsoft.SharePoint.Client.CamlQuery
$query.ViewXml = "<View Scope='RecursiveAll'> " +
"<RowLimit>5000</RowLimit>"+
"<Query>" +
"<OrderBy>"+
"<FieldRef Name='FileLeafRef' Ascending='True' />"+
"</OrderBy>"+
"<Where>" +
"<Eq>"+
"<FieldRef Name='FileLeafRef' />"+
"<Value Type='File'>EDMS API/APICAL Invoice</Value>"+
"</Eq>"+
"</Where>"+
"</Query>"+
"</View>"
$listItems = $list.getItems($query)
$context.Load($listItems)
$context.ExecuteQuery()

Answer 1

Most likely it's not an RowLimit issue but rather the Query expression itself. The query:
<Where>
<Eq>
<FieldRef Name='FileLeafRef' />
<Value Type='File'>{value}</Value>
</Eq>
</Where>
returns items those names match {value}, which in turn does not return the files located under a specific folder which url specified in {value}.
If you want to include only files located in specific folder you could consider at least the following two approaches.
Assume the following structure:
News (sub site)
|
Documents (library)
|
Archive (folder)
Then the following examples demonstrate how to include items from Archive folder:
1 Set folder via CamlQuery.FolderServerRelativeUrl property:
$query = New-Object Microsoft.SharePoint.Client.CamlQuery
$query.ViewXml = "<View Scope='RecursiveAll'> " +
"<RowLimit>20</RowLimit>"+
"<Query>" +
"<OrderBy>"+
"<FieldRef Name='FileLeafRef' Ascending='True' />"+
"</OrderBy>"+
"</Query>"+
"</View>"
$query.FolderServerRelativeUrl = "/News/Documents/Archive"
$listItems = $list.getItems($query)
$context.Load($listItems)
$context.ExecuteQuery()
2 Set folder via FileDirRef property
$query = New-Object Microsoft.SharePoint.Client.CamlQuery
$query.ViewXml = "<View Scope='RecursiveAll'> " +
"<RowLimit>20</RowLimit>"+
"<Query>" +
"<OrderBy>"+
"<FieldRef Name='FileLeafRef' Ascending='True' />"+
"</OrderBy>"+
"<Where>" +
"<Eq>"+
"<FieldRef Name='FileDirRef' />"+
"<Value Type='File'>/News/Documents/Archive</Value>"+
"</Eq>"+
"</Where>"+
"</Query>"+
"</View>"
$listItems = $list.getItems($query)
$context.Load($listItems)
$context.ExecuteQuery()
