AutoCAD users sometimes discover that when they try to Save or Open a drawing, no familiar Save/Open dialogue box appears. Instead, the command line prompts “Enter file name:” and you must type a name. This usually happens because the FILEDIA system variable has been switched off (set to 0). Quadra Solutions experts emphasise that this is a common, easy-to-fix issue – not your fault – and can be resolved in seconds.
What is the FILEDIA setting?
In AutoCAD, FILEDIA controls whether file dialogue boxes are displayed. When FILEDIA = 1, AutoCAD shows the normal graphical dialogues; when FILEDIA = 0, the same commands use the command line prompts instead. As the AutoCAD documentation explains: “0 does not display dialog boxes… 1 Displays dialog boxes.” For example, with FILEDIA=0, the SAVEAS command will prompt you on the command line instead of showing a dialogue box.
This setting often flips to 0 after a crash or interrupt. In fact, a support blog notes that in some AutoCAD versions the FILEDIA variable can reset to 0 if commands are interrupted, causing the file open/save dialogues to vanish. The key point is: this behaviour is common, not a random bug, and can be fixed easily.
How to restore the Save/Open dialogue
Fixing this issue is straightforward:
- Type FILEDIA at the command line and press Enter.
- When prompted “Enter new value for FILEDIA”, type 1 and press Enter.
- Now try Save or Save As – the normal dialogue box should return.
This step flips the switch back on. As one expert explains, typing FILEDIA and setting it to 1 will cause the dialogue boxes to appear again. AutoCAD forums similarly note: “To turn FILEDIA back on… at the command prompt type FILEDIA. Then type 1”. After doing this, the usual Save or Open dialogue window will open normally instead of the command-line prompt.
Why this happens – and why you shouldn’t worry
Many beginners worry they have broken something. In reality, FILEDIA often changes unintentionally. It might happen if a programme crashes, or if someone runs a script that does not restore settings. One blog explains that FILEDIA resets can occur if commands are interrupted. In short, it’s a known quirk, not your fault.
Remember: this issue is very common. The fix (typing FILEDIA then 1) is quick and easy – even for beginners. Once fixed, you can save normally. There’s no harm done, and knowing this tip will save you time in future.
