Hi Ryan, In the meantime I solved my unicode problem by simply setting FDConnection.StringFormat = unicode (I thought it was the default value but in my environment I have to choose it actively. (I could also solve the problem by choosing to use NVARCR instead of VARCHR) So here are my FDConnction1, fdqGloser (FDQuery) and dsGloser (DataSource):
object FDConnection1: TFDConnection Params.Strings = ( 'Database=C:\SQLite\flashcard.db' // THIS WAS CHANGED... (read only problem solved) 'StringFormat=Unicode' // THIS WAS CHANGED... (unicode problem solved) 'DriverID=SQLite') LoginPrompt = False Left = 36 Top = 104 end object fdqGloser: TFDQuery Connection = FDConnection1 SQL.Strings = ( 'SELECT * FROM Gloser') Left = 116 Top = 104 end object dsGloser: TDataSource DataSet = fdqGloser Left = 196 Top = 104 end Thank you for the help so far.

Usually the FireDAC connections work fine out the box, especially for SQLite (though I suggest using your own latest DLL which can be downloaded from sqlite.org). There are 2 typical reasons why a file can have locking difficulty in Windows: 1 - Windows UAC is virtualizing the folder your DB is in (did you perhaps put it in the same folder as the exe? Or any other Windows-system folder?), or 2 - An over-zealous anti-virus is locking the file. Now I'm having difficulty believing it's 2, because the DB is not "Busy" or erroring out when opening, it's "Read-Only" which isn't an automatic switch for sqlite itself or via FireDAC. I'm also confident it's not 1 because the Windows UAC virtualization could move the file, could even redirect to a folder where the file doesn't exist, but I have never experienced it causing the file to open in read-only mode in sqlite. This leaves only the FireDAC component itself. Perhaps it has read-only mode set in either the properties or connection parameters - could you post for us your exact set-up of the FireDac connection? (Just say which controls you've used and their properties, view the form as text and copy it if needed). Just to be sure it isn't the UAC, try and connect to an sqlite DB or file in a safe location (such as your documents folder), see if you have any luck. These things usually work rather easy and straight-forward - so I'm betting it's something small that's perhaps not obvious.
